I have two sons old enough to shoot and wanted them to have a little fun. I figured I would build them each AR 15's. The first one I built from parts using a Stag as a platform, added a DPMS trigger system, Sarcos flat top, Sarcos aluminum free float hand guard, Pac Nor 1/9 barrel and a host of true mil.spec parts, oh yea, one of those spongy things you stick on the stock to help you keep your pretty face locked solid. The only thing special to this build was to re-cut the barrel crown to 11 degrees with a stand-off outer ring to prevent damaging the crown. I sealed in a 3 oz. mercury switch into the stock pocket to eliminate and felt recoil. I put on my target scope (Barska Tac). This gun shoots around .75" groups off the bench with 62 gr green tips.
The second build was on a Bushmaster XME2/15. The gun shot p.o.i. with the sight bottomed left. I couldn't let that go, so I replaced the top receiver with a Sarcos flat top, aluminum free float hand guard, DPMS trigger and another one of those spongy things. I cut off the muzzle break and turned the barrel the same as described above and installed a new muzzle break. Put the thing together then put on an Ultra Dot. I added a mercury switch to this one too. This one shoot average groups of 1.5" with the 62 gr. green tip ammo.
Overall these guns perform flawlessly. I enjoy shooting them as much as the kids, but, the kids will be buying there own ammo from here on out.-SDH:cheers:
