You will need a barrel vise and a torch they have some serious loctite on them. Place it in the vice heat the break and twist it off. If you don't use a barrel vice your in danger of damaging the aluminum reciever.

my next .22 is going to be a Savage mk2 trr-sr bolt gun.

My sr 22

mods stock grip full length top rail bipod optics cantilevered riser flip up rear peep so far... flash hider is factory. I have done the paper work and paid the tax stamp for a .22cal suppressor (Advanced Armament Element) but it's probably still about 3 months out.

I managed 3/4" groups at 50yds after a quick zero I know the rifle can do better but I have only run 35rds through it as I have been working out of town and seems every time I manage to get home it decides to rain ALL weekend.

it's Magpul P.R.S. you will have to replace the m4 tube with an a2 buffer tube you can pick up the A2 at Brownells for $15.00 or so

Thanks rodent.22, the colt m16 wont work either as it has no tube at all my local dealer disassembled one for me so I opted for the ruger sr22 instead but i really like the m16 spr and brownells has an awsome but expensive stock with a built in folding monopod and adjustable cheek peace so I may still pick one up.

I am confused rightofwayman you are the owner of ironeagletactical and have stated that fact on this very forum so why would you say I have checked out your stuff and I am interested but the attempt at deception no matter how slight is unwelcome , unprofessional and sets doubt in my mind as to whether or not I will be treated honestly and fairly in a buissiness transaction with you.

still no reply?

If you've fired enough rounds through a rifle with a red dot then you've noticed that you must keep the dot centered in the tube for consistant grouping. You must also maintain a consistant cheek weld. I myself don't cowitness my iron sights actually I ignore the front sight altogether and simply look through the rear apeture at the dot this forces me to center the dot and repeat my cheek weld without thinking about it. I shoot with both eyes open and while I can aquire a target slightly faster with a dot only I produce more accurate shots using the rear apeture with minimal lag in target aquisition.

@Techmike, That's strange because I recently installed the unit myself with great results. Before I averaged 1" - 1 1/4" groups @50yds now most of my groups can be hidden by a nickel. Maybe it's an inconsistency in there machining process. Sorry about your bad experience maybe you could contact them tell them your problem and have it replaced. Improved accuracy is one of there product descriptions after all. I myself couldn't just suck up a $70.00 loss without some serious bitch'n at anyrate.

Just wanted to show off my new rifle.

Thanks, shoots great with nitceably noticeably tighter groups at 50yds than with factory muzzle device. I just installed the compensator today. I'm going to make a range card out to 200 yds tommorrow.

A couple Pics of my m4 ops.

Do any of you guys use it and if so have you experienced any of the advertised benefits such as increased accuracy?

Thanks for the info guys but the SPR has an a2 buttstock. I don't know if it uses the same buffer tube as the Umarex m4. The milspec A2 buffer tubes are completetly cylindrical and the magpul PRS is a fixed stock that Requires an a2 buffer tube. Thanks again

Hello, I own the m4 ops model but I'm considering a purchase of the m16 spr version but that decision depends on one mod. Does any know for sure if I can install a magpul PRS stock on that rifle or any of the Umarex/Colt designs?

Hello, First let me thank the administrators for putting together this site and it's members for participating as I have found not one other useful or informative site regarding the umarex/colt line of firearms. Back on task, I have the m4 ops model and have sent just shy of 20,000 rounds down range. I clean my rifle every 500 rds give or take. I have never completely dissasembled the rifle as per techmike's .ppt but that project is on my short list. I have experienced no problems with this rifle other than an an initial search for quality ammo after about $30.00 and seven mfg's I settled with the federal 550 value pack and have experienced 0 feed problems. I routinely fire sub M.O.A. groups @ 100 yds with this $15.95 economy ammo. I currently have no mods other than a $49.00 centerpoint 1x red/green dot scope I Picked up at Walmart which has a signifigantly smaller/tighter dot than the Usual 5 M.O.A. found on most econo optics. It's not labled but I'm guessing it's likely around 3 M.O.A. I'm quite pleased and impressed with the rifle rifle and I'm considering purchasing the m16 spr model if it will except the mods i want to outfit it with so now I'm off to the mods and upgrades section to search for tips.
