Very glad to have it - Pantheon Arms Kentri 3.5N AR-15 Short Buffer System

Okay, the Pantheon Kentri worked flawlessly when I got it to the range. 100% reliable; ejection seemed more forceful but so did bolt return, so ... well, it works great. It's more difficult to fully retract and lock open the action with the Kentri installed. I found it cheeked fine with a small bit of foam for spacing, and that the slung gun ran great and was perfectly accurate when fired offhand standing on my hind legs. It's pretty nifty how the Kentri buffer system works, utilizing the space in the BCG itself. This does require a different takedown (unscrewing/removing and NOT punching the pin until everything's removed), and decades of doing it the regular way have me worried I'll bollix it (so I taped over the rear pin to remind myself). It sure does shorten the OAL of the pistol into a handy little blaster: a number of onlookers gathered to check it out.
