AC_DC Posted November 13, 2015 Report Share Posted November 13, 2015 Quick question for the experts here. If the 80% lower already has the rear take down area milled for the rear lug, is it alright to just mill the fire control pocket? Will there be any functionality issues?For reference, I've read this can be done with AR-15 builds (https://www.ar15.com/archive/topic.html?b=3&f=4&t=675681), but I'm not sure if this is also true for 308 builds.Thanks!

slugger43 Posted November 13, 2015 Report Share Posted November 13, 2015 (edited) That's a very nice looking job. I did two 308 lowers with the 80%Arms jig using a router. What kind of tool and/or jig are you using? I'm not the guru on these things, but I strongly expect to do more of them. The rear shelf was real easy to do, but I don't know why you would need to cut out more than you already have, so long as the fire control group fits in the hole and works okay, although I've never seen it done that way.I suspect I'd cut it out just because that's the way I've always seen it. I'm not big on re-inventing the wheel. My 80% lower did not have the rear area already milled out.

EasyEJL Posted November 13, 2015 Report Share Posted November 13, 2015 I don't see any functional/mechanical reason it's necessary, but i'm not sure Quote Link to comment Share on other sites More sharing options...
unforgiven Posted November 14, 2015 Report Share Posted November 14, 2015 I could be wrong but on some AR15's the lower has a deeper self for full auto parts.For this : http://www.quarterbore.com/nfa/dias.html Quote Link to comment Share on other sites More sharing options...

ChaseFan9 Posted November 14, 2015 Report Share Posted November 14, 2015 And good luck finding a DIAS, I've heard some pretty scary stories about their legal status.... Quote Link to comment Share on other sites More sharing options...
Donkeyjoe Posted December 2, 2019 Report Share Posted December 2, 2019 Really late to this and I’m sure probably nobody watching this but most lowers I’ve seen from factory’s I.E. colt,Springfield armory, century arms, Daniel Defense etc... only have the two separate pockets. It’s probably not going to net much gain but I’d imagine leaving that material in place would make a more rigid lower which equals accuracy/better functionality. Just my thoughts tho.
