I received my brick of 60gr. monsters yesterday and shot 40 rounds thru my Colt this afternoon. Thankfully, they held a pretty tight group at 38 yds. (at least tight for me, as I'm shooting left-handed, sighting with my left eye because I have a severe cadillac in my right eye and left eye ain't too good either). Only had one failure to fire because the bullet didn't seat fully in the chamber. Turned the spring in another five turns, cleaned the chamber with a Q-tip and #9, and so far, ni more problems. 40 rounds actually moved my steel bullet-catcher back about 2 inches on the bench! Nothing else I have shot has done that before. They seem to back quite a PUNCH! They were a lot of fun to shoot because they have a really cool sounding POW when they go off (NOT quiet), and they have a distinct recoil compared to other rounds. The smell is horrendous, and will burn your eyes. Brother Bill says it's the Ely primer. I think some of you guys with the Umarex/Colt ought to try them! No sign of "key-holing" with my rifle. By the way, I'm scheduled to get that Cadillac removed from my right eye on Oct. 5th. I am scared shitless! Wish me luck!

I'm not so sure I would have ignored the voices in my head saying: "PULL THE TRIGGER"! That would at least have ended ONE asshole's criminal career, and saved the tax-payers a fortune! (we were probably supporting him anyway)

Well I just ordered a 500 round brick of these from CTD for $38. I also ordered some stuff for a friend of mine, so he's paying most of the freight. This was the deal I was waiting for! I really hope I don't wind up EATING these little bastards 'cause they don't work!

This goes back to one particular lawsuit involving 4 or 5 kids (teenagers and one adult) who were playing (drinking) on "High Bridge" in Prince Edward County, Va., not far from where I live. They call it "High Bridge" because it's............HIGH!! A couple hunnerd feet I would guess. With "NO TRESSPASSING" and "DANGER" signs everywhere, these dumbasses had gone out so far on the bridege that when the train came, GUESS WHAT?? " They got run over by a damned ole TRAIN" (or jumped to their demise). One more "GUESS WHAT"??.....Their parents sued Norfolk-Southern Railroad, and got a several-million-dollar settlement!!!! We are breeding IDIOTS so LAWYERS (and the idiots) can get RICH off of our fucked-up JUDICIAL SYSTEM!! It's damn NEGLIGENT of our railroads to allow people to get hit by a TRAIN, just because they were on the TRACK!!!

Hey guys, I just wanted to show you my new NcStar GREEN laser. I've been having a BLAST with this thing! Once I figured out the characteristics of "laser + POI", it has been a really cool addition to my Colt. It takes only seconds to zero-in by simply lining up the green dot with the scope crosshairs at your average shooting distance. After that, it's easy to compensate for other distances, once you figure it out. The beam is clearly visible in daylight, and in low-light, or darkness, it's amazing! Got it from CTD for around 50 bucks, and 10 for the offset mount. It's a lot of fun to just hold the rifle at your side, and mow-down a row of beer cans, and have even blasted a few squirrels with it!

Apparently the hole in the end-cap on mine must be slightly oversized on mine, as there is play where it fits over the barrel. I replaced the oring, and can feel it engage the barrel shroud when screwing it on. Not worried much about "modifications", as it sure ain't no suppressor. Using subsonic ammo has made all the difference in the world as far as noise goes, and the set screw has seemed to provide a tighter group at 38 yds. after further testing since last post.

Since some of us are actually interested in learning something, my "genius" brother hooked me up with another idea that improved my POI. I have the Colt/Umarex "Compensator" on my rifle, which I like the looks of, and it reduces the report considerably (with a little "help"). This compensator partially slides OVER the barrel, and has a threaded "bushing"? that fits rather loosely over the barrel at the back-end of the can. When I described this loose "rattly" fit at the end of the compensator to brother-man, he said: "YOU GOTTA GET RID OF THAT SLOP! PUT A SET SCREW IN THERE TO STABILIZE THAT THING!!" So I did. Drilled and tapped a hole in the threaded end-cap/bushing and installed a 8-32 allen set screw, and snugged that sucker up. Guess what, noticeably tighter 20-round groups, with NO fliers (so far). Apparently, something rattling around on your barrel screws things up also. Yep, I'm still learnin'! Those of you who have the Umarex "Compensator" might want to consider this simple upgrade. Just tap on the rear-end of it when it's installed, and you will hear it rattle against the barrel.

I seem to have stabilized the accuracy a little by moving the gas block a little further away from the foregrip. I believe they may have actually been touching. I slid the block forward enough to slide a credit card between the two. Should replacing the sight with the lightweight aluminum gas block have changed the "floating" characteristics of the barrel?

Actually, attaching the bipod to the handguard affected POI LESS than on the gas block, but did raise POI about an inch. Brother says rigid bipod on rigid surface can cause barrel to "bounce", throwing off accuracy. I wonder if the barrel-within-a-barrel setup on the Colt is more, or less, succeptable to this? I wonder if extra tension on the flash suppressor would change this affect?

Not too long ago, I installed a UTG bipod on my Colt/Umarex m4 carbine. At first, I put the rail-mounted bipod on the bottom rail of my Umarex free-floating quad-rail foregrip. I immediately noticed I had to re-zero my scope at 40 yds. (the distance of my "range" in my back yard.) I said something about this to my brother, who has been an avid target shooter for MUCH longer than me, and he told me that using a bipod, as opposed to soft bags, will ALWAYS change the point of impact. Well, I told him he was fullashit. It just didn't make sense to me that WHAT you were resting you rifle on would actually CHANGE where the bullet hits! Well guess what? I recently removed the front sight, and installed a gas-block quad-rail in it's place (the front sight was visible through the scope). This is when I decided to re-mount the bipod to the bottom rail of the gas-block. BAM-BAM-BAM, shooting 2 inches high! My brother made me look like an idiot again! Have many of you shooters out there experienced this also? It seems the closer to the barrel the bipod is mounted, the HIGHER it shoots. Is this a common result, or does this vary from gun-to-gun? I also found out the rigidity of the SURFACE that the bipod rests on also makes a difference on POA. This is mind-boggling!

I too like Colt. It feels very "hefty" compared to many others. I have heard/read from a lot of folks who have purchased NEWER versions, that most of the older "bugs" have been corrected. They now have functioning dust-covers, stiffer bolt springs, 90-degree safety levers, and improved chamber contours that accept a wider range of ammo. Even the dreaded REMINGTON! I just wish they would sell me the necessary parts to upgrade mine!

Are you saying they cycled reliably and did not "tumble" in your Colt M4? I have a Colt/Umarex M4 also, and really want to try them. CTD has them in 500 round boxes only for 30-something bucks. Should I go for it? Every now and then I go on "bullet-buying-binge" because I worry that one day soon, we won't be able to get them at all!

Looks like Cheaper Than Dirt has Winchester M22 (.22lr 40gr.) in 2000-round cases for $77.00! To those of you who have tried them: what do you think? Winchester claims they are "AR-format" specific, and designed for improved cycling and accuracy. Am I going out on a limb by buying 2000 of these boogers for my Colt/Umarex M4? Of course, I'll have to wait till I need to order some more "stuff" so I can offset the ridiculous UPS shipping on ammo!

That seems very strange to me. Winchester 555's and Subsonics shoot extremely well in my Colt. The rounds chamber and eject flawlessly, and always have. I would suggest you have a bad batch. Winchester more than likely will replace them for you.

I used the Colt/Umarex accessory "RIS" (rail interface system) foregrip. Got it from Cheaper than Dirt for almost half the retail price.

I wish I had figured that one out 30 years ago!

HOLY SHIT!!

For me and my Colt, Winchester Subsonics shoot more consistently accurate than anything I've tried. High-velocity bullets seem to get squirrelly after about 70 yds. The relatively heavy (40 gr.) bullet seems to fly VERY consistent, even at long ranges. It seems when a small bullet breaks the sound-barrier, then slows down, they tend to get erratic, and .22 High-velocity bullets seem to slow-down rather QUICKLY. Has anybody else experienced this? Or am I fulla sh--?

It seems to me that one of the biggest design flaws in the .22 rimfire cartridge is the PRIMING material not being fully distributed around the circumference of the rim, causing frequent misfires. What if someone designed a "fork-like" firing pin that was single on the hammer end, but DOUBLE on the striking end? That would enable the rim to be stuck in TWO opposing places AT THE SAME TIME. Wouldn't that reduce the frequency of misfires by nearly 100 percent? Like hitting each primer TWICE with each shot? Looks like a small design change in most bolt assemblies could make this possible. How many times have we extracted a misfired cartridge, only to rotate it a few degrees, re-insert it, and BANG! A double firing pin would fix that........RIGHT? Did I just come up with a f...ing brilliant idea or WHAT?! P.S. If the pins are close to 180 degrees apart, the ignition would be more complete also, reducing unburned powder, and the "BANG-BANG-BANG-pop-BANG-BANG-pop" syndrome! I just came up with the idea. Now somebody needs to design and build it......and make me RICH!

I decided to mount the laser directly under the barrel, on the gas block rail, which is considerably closer to the bore than the foregrip rails. Now I only have to worry about elevation. With the laser so much closer to the barrel than it was, the differences between dot and crosshairs is not so drastic. This really kinda opens your eves to the peculiarities of the AR sighting format when using optics on the carry handle, open sights also, involving the distance between the barrel and sights! The higher the optics are from the barrel, the smaller your "window" is for POA. I guess that's where the "bullet drop compensators" come into play. The one on my scope comes in really handy when shooting at targets that are too CLOSE (believe it or not). It actually keeps you from shooting about an inch or so too low at short ranges.

Ok, so I just broke down and bought me a little green laser sight and a 45 degree offset mount to go on my Colt/Umarex M4's quad-rail gas block. It's installation and operation is pretty straight forward, and I first sighted it in at about 20 yds. so the laser dot and the crosshairs on were both on target. It didn't take me long to notice that the dot and the crosshairs were only on target at TWENTY YARDS! As the distance changed, the laser and the scope gradually moved apart. So my question is: when people such as Law Enforcement and Military rely on lasers (like they do in HOLLYWOOD), how do they keep them sighted-in at varying distances? If the laser is mounted on the left or right side of the barrel, the dot wanders to the left and right, according to the distance, of course the dot goes up and down vertically as well. There seems to be a very limited "window" to where the bullet and the laser actually intersect without further adjustment. So how is it feasible to use these things in the field at all? I like pop my pecan-eating squirrels every now and then, but I can't get them to stay in that 20 yard range!

Believe it or not subsonic and hyper-velocity rounds shoot very well in my Colt, just not the CCI or Remmington versions. Winchester and Aguilla subsonics are VERY accurate to 70 yds. (which is as far as I've tried them), and are very quiet when suppressed. They cycle and chamber very well even with the bolt spring tightened all the way in. The Winchester's "truncated cone" 40gr. hollow point packs quite a PUNCH for a slow-moving bullet. The squirrels don't even know what hit 'em!

I'll have to get back to you on specs. Took barrel to my local gunsmith to see why some bullets were having trouble chambering. I had just bought a box of CCI Subsonics, and a box of CCI Velocitors. Both had trouble chambering all the way after a few shots. I was shown the measurements of the CCI bullet CONTOUR, demonstrating that it had a slightly LONGER contact area than other bullets. He showed the chamber had a slight taper to it, and had several .22 "pilots" for chamber finishing tools that would not enter the bore due to it's undersize diameter. He told me, that for accuracy purposes, all this was a "good" thing, but not necessarily so good for semi-auto cycling of some bullets. In front of me, he inserted these same pilots into a Ruger 10/22 barrel, and a couple other "American-made" barrels, and they slid into the bores and chambers easily. So did the CCI bullets! He even pushed some sort of lead "blank?" thru my barrel and measured the "lands & grooves?", and showed me a smaller diameter than the other barrels. He said this barrel would be "great" in a bolt-action gun where the rounds are "shoved" into the chamber, guaranteeing a tight fit. Sorry I can't be more specific, all I remember is a "go, no-go" situation. He offered to get a special chamber reamer to loosen things up a bit, but I opted NOT to, I would just stick with ammo that worked. I figure TIGHT is better than LOOSE any day!

I have found the chamber to be slightly UNDERSIZE compared to many other (particularly American made) .22 semi-autos. Have read that many European-made barrels are tighter than what we call "standard". The Walther/Colt's bore diameter is smaller too. Specs closer to "match-grade". The Blazers I tried, like the Velocitors would begin to "stick" in the chamber about 3/4's in. Sometimes cleaning the chamber after every 5 shots would help, but that was WAY too much trouble! If you mike the diameter of some CCI's bullets, you will see they are larger, or have a different "contour" than others. When the bullet doesn't seat fully in the chamber, the result is a "light-strike" causing misfire. Often when this happens, the un-modified extractor on the Colt will not even pull them out. The CCI's can work well in "sloppier" barrels, but not in my Colt. Measure the bore and chamber dia. on the Colt, and compare to Ruger and others, you'll see what I mean! I that's why a 10/22 will shoot most anything, even Remmington!

I had an opportunity to try some Blazers not too long ago, but they were too tight in the Colt's chamber, causing misfires. Had to pass on those, even if they were cheap!
