Fitting a blow back bolt ejector to a lower
« on: August 09, 2017, 06:51:19 AM »
I see glock magazine 45acp lowers fitted with the ejector for a blow back bolt system.
Any body done this with a cnc lower, and have machinist spec ?
Thanks, Jim

Colt pattern blowback upper isn't compatible with a CNC AR45 lower. Mag sits too low in the magwell and no where to put a feed ramp.....I DO have something in the works as far as blowback....just short handed and not enough machines...... ;) we are working on it.... However the DI45 runs exceptionally well .... www.maconarmory.com
