Needed one to take to the range. This one will fit the bill.

Was looking for a .308 carbine buffer tube that I could use standard length buffers instead of the shortened buffer in a standard carbine buffer tube. I have several H2 buffers. This buffer tube is longer than a standard carbine buffer tube. Great for people with longer arms too. Six position adjustment. When stock is in shortest position there will be an inch or so of the buffer tube exposed.

Unless one wants to pin or indent the bottom of a barrel, this is the way to go. I have this product on 2 guns.
A little instalation tip I learned. Get a piece of spaghetti and stick it in the gas hole on the barrel. Break it off so it doesn't stick out above the top of the gas hole. Slide the gas block over the barrel until it can't go any further. Tighten the screws on the gas block, but make sure it can turn back and forth. Flip the barrel over. Turn the gas block or barrel back and forth until the piece of spaghetti falls into the gas hole on the block. Leaving the barrel upside down,turn the gas block gently back and forth slowly until it stops both ways. Center it in the middle and tighten the screws. This Is important so the spaghetti will fall out and the gas block is centered over the hole. After tightening block turn barrel over and use a cleaning rod to break the spaghetti off. Both pieces will fall out. There ore several different sizes of spaghetti.

I bought one of these years ago and built it on the AR15 platform using a PSA upper and lower. One can buy a .22 look alike AR, but building it on the AR platform one cannot distinguish it from the real thing. I installed a teardrop forward assist which will not function as well as Magpul furniture, front sight base along with a carbine gas tube that of course will not work since it is blowback. A colt carry handle and side sling mount. I also added a 3.5lb 2 stage trigger. I prefer single stage triggers but I have a few 2 stage lying around. The gun works very well, including subsonic .22 through a borrowed suppressor. When I get around to it I will also build this one. Since the CMMG .22 has the A4 profile barrel I will keep it that way and add a pinned front sight base instead of a free float handguard. The barrel is 16.1" but it goes further into the upper than a 5.56 barrel so it does not stick out past the sight base as far as a 16" 5.56 legal carbine barrel does. The barrel it threaded 1/2-28 so any muzzle device will work. I have an A2 birdcage on mine, not tightened of course. CMMG recommends a certain trigger, but the aftermarket 3.5 LB one I put in it works good.
