Thanks wobblinwheel I checked the bolt that holds the grip on and it was a tad lose . I also tightend the muzzle brake just a tad bit more and seems pretty good now.

Hay guys I have a newer colt m4 carbine and was wondering if anyone else has lose take down pins? I can push my out with my finger and there is play between the upper and lower. The gun only has 1000 rounds threw it and has been cleaned twice . :confused:

Ya wobblinwheel this gun runs perfect so far .I actully started with an ISSC mk22, what a heap that was .The store that I bought it from let me exchange it for the colt m4 carbine . I don't now if I ever want to shoot the remingtons they are a pretty dirty round.I really like the CCI mini mags and the blazers .I would like to try the new winchester m-22 rounds to see how they stack up. Thanks cmsm4colt

Hay wobblinwheel the first time i feild stripped it i noticed that the screw for the bolt speed adjustment was 3 1/2 turns in from flush from the factory. It fires mini mags and blazers perfectly so I am hesitant to change the setting. like I said this gun runs great ! Lovin it ! Thanks for the info :)

Hello from wisconsin . Bought a ISSC MK22 a couple of weeks ago and what a nitemare.The first time I went to shoot it would not fire and went down hill from there. I bought the gun from Dunhams sporting goods in Delavan WI and called and told them my Issc mk22 didn't work ! They agreed to take it back and let me buy a Colt m4 .22 carbine . This gun runs great and I'm having a blast .Lots of good info on here and I like the site alot . :grin:

Hay guy just wanted to give an update on my new m4. I've put 500 rounds of cci mini mag roundnose and 500 cci blazers threw the gun and it has been flawless !!!!I really love this gun it's fun to shoot and cheap to shoot as well !! :thumb: Thanks cmscoltm4!

I found a rail that will bolt to the bottom of my carbine hand guard on ebay for 10.00 that will allow me to use a bypod when at the range . Thanks for the help guys !

Hay guys does anyone know what quad rails will fit the m4 carbine delta rings ? I would like to change out the plane front hand guards with a quad rail system that works with the delta rings that won't brake the bank .Thanks ;D

Hi guys I'm new to the forum . I just bought A ISSC MK 22 and it wouldn't fire at all the store I bought it from took the gun back and let me trade it on a colt m4 carbine .after 250 rounds of cci mini mags and 250 rounds of cci blazer I have not had 1 probelm with the gun functions perfectly . I belive I have an updated version . The saftey is 90 degress and dust cover works also the buffer does not fall out and the bolt realse won't fall out either. The first time I feild stirped it and cleaned it i noticed the bolt spring was turned in for high volocity . After my issc nightmare this gun is a caddy!! lovin it :)
