atomichead Posted May 12, 2011 Report Share Posted May 12, 2011 I want to remove the front sight on my M4 Ops. Looks like there are two roll pins to push out but it also looks like they go through the barrel. Has anyone remove this sight? Does it leave two cosmetic holes?

techmike Posted May 12, 2011 Report Share Posted May 12, 2011 It leaves butt ugly holes. But that is not the barrel, it is just a shroud that the actual barrel fits inside of. I mixed up some agraglass and filled the holes, sanded to match the barrel's barrel shroud's contour and dura coated it. If you are not familiar with it, agraglass can be had from Brownells, and is an epoxy type material that won't dry up, crack or fallout.Good luck!TMPS - Post some pics when you get-er done!

atomichead Posted May 12, 2011 Author Report Share Posted May 12, 2011 Hmmm... filling, sanding and finishing sounds like too many things I can screw up. Do you know if anyone makes a flip down sight that fits the same hole pattern? Quote Link to comment Share on other sites More sharing options...
rodent.22 Posted May 13, 2011 Report Share Posted May 13, 2011 All I've seen go on a rail. :confused: Quote Link to comment Share on other sites More sharing options...
techmike Posted May 13, 2011 Report Share Posted May 13, 2011 Negative on anything with the same hole pattern. Quote Link to comment Share on other sites More sharing options...
wobblinwheel Posted May 13, 2011 Report Share Posted May 13, 2011 Umarex makes a fold-down sight that pins the same way. I think the best solution is to get the $20 clamp-on gas-block/quad-rail and the rail-mounted sight (also about $20, I think). This arrangement covers the ugly holes, and gives you the option to use a multitude of sights, bipods, lasers, etc. Most come on and off with just a thumbscrew. Also, it has a place for the original sling swivel. I believe acompany called UTG makes this stuff. Quote Link to comment Share on other sites More sharing options...
atomichead Posted May 14, 2011 Author Report Share Posted May 14, 2011 $95.50 for the Umarex flip up is a little rich for my blood. Think I'll try the UTG rail/sight combo. Thanks guys. Quote Link to comment Share on other sites More sharing options...
wobblinwheel Posted May 14, 2011 Report Share Posted May 14, 2011 Cheaper than Dirt has the Umarex front flip sight for $43.90, if you're interested. Quote Link to comment Share on other sites More sharing options...
atomichead Posted May 14, 2011 Author Report Share Posted May 14, 2011 That's a different sight than they have on the Umarex website. I'm really just trying to get the sight out of view of my red dot so whatever works, looks half decent, doesn't leave behind messy holes and doesn't break the bank wins. The CTD sight should do the trick. Quote Link to comment Share on other sites More sharing options...
rodent.22 Posted May 14, 2011 Report Share Posted May 14, 2011 The Leapers red/green dot scope has a built-in base that clears the front sight, $69.95 at Amazon.com. Quote Link to comment Share on other sites More sharing options...
Microgunner Posted May 14, 2011 Report Share Posted May 14, 2011 I use the Walther PS55 sight on my Colt/Umarex. Like the Leapers it uses the battery compartment as a riser to clear the front sight post and it works well. It's the sight Colt uses in their ad campaign photos.

atomichead Posted May 15, 2011 Author Report Share Posted May 15, 2011 It was all worry for nothing as I replaced the Walther PS-55 with an NcStar 4x32 Tactical and the sight is now cleared. Love it when a plan comes together. Quote Link to comment Share on other sites More sharing options...
wobblinwheel Posted May 15, 2011 Report Share Posted May 15, 2011 I use an NcStar 4X32 "tactical" scope as well, but in some cases I could still see an annoying "shadow" of the front sight. Sight had to go. Now I still can stick it on there when I use carry handle and open sights. Takes about 20 seconds for the switch. Quote Link to comment Share on other sites More sharing options...
atomichead Posted May 17, 2011 Author Report Share Posted May 17, 2011 Yeah, I noticed that shadow as well. And I can't really get a good focus. A true case of you get what you pay for. The PS-55 was clear and easy to use, just no zoom. Can anyone recommend a good red dot with around 3-9x zoom that cost less than $150?

techmike Posted May 17, 2011 Report Share Posted May 17, 2011 This http://swfa.com/Leatherwood-1-4x24-CMR-Tactical-30mm-Rifle-Scope-P45852.aspx is what I have on my Colt and my AR. I am VERY pleased with them. Zoom is 1 to 4, it has a green illuminated-dot-in-a-doughnut. (click on the small reticle picture to enlarge) The illumination is not very useful on a bright day, but the scope is entirely functional even if the battery goes dead. They cost $250 ea when I got mine. The ranging reticle is obviously for 5.56 and not .22lr... on the Colt I have mine sighted in @ 50 yds, and depending on the ammo I am using, dial the top turret to 6 and it is right on at 100 yds.TMPS-Nice looking rifle!

atomichead Posted May 21, 2011 Author Report Share Posted May 21, 2011 Does anyone have experience with Sightmark? They have a reflex sight and separate magnifier that looks like an EOTech setup but at 1/6 the price. Quote Link to comment Share on other sites More sharing options...
asmurff Posted May 21, 2011 Report Share Posted May 21, 2011 I've not used one, but one of the guys I shoot Tactical Rimfire matches with uses one on his 10/22 and he does very well.I thought about getting one for my Browning Buckmark, but decided I didn't want to go down the optic road with any of my pistols.
