Put this guy together last night and I can't wait to finish the upper and shoot this thing.
All the parts laid out to make sure I wasn't missing anything......I was. Had to steal a buffer retaining spring and retaining plug from another gun.
Spikes 9mm Glock Lower, KAK shockwave kit, MEGA trigger, K2 grip, BAD ambi safety, 8.0 oz 9mm extended buffer, CMC Anti Walk Pins(these will not work with the MEGA trigger. Either the pins are slightly oversize, or the trigger holes are slightly undersized. It would work with standard pins, but decided the anti walk pins were more inportanat to the build, so no MEGA trigger in it yet. Might try to open up the holes in the trigger just a bit to make them work.
Spikes Slick Side upper, BCM Mod 3 CH, Spinta 9mm bolt
BA 5.5" barrel 1/2x36, KAK slimline Muzzle Brake, BCM KMR-A 7", crush washer(to time the brake so the slots are at 3 & 9 - yes, I'm anal)
Upper mock up to see how it will all look.
Lower complete, Upper mocked up. Just need a vice and the upper will be done, hopefully by Sunday so I can shoot it.
Manually cycling it with an empty mag did cause the bolt to lock back, so very happy about that. Will know if it really works once I get to the range.
So far this has been my easiest build to date, just the 1 small annoyance with the MEGA trigger not working with the CMC pins.
