Ive recently got a new 20" .450 upper. Right now its barrowing my 7.62x39 lower until I get a dedicated lower built for it. The barrowed lower its on now has a standard carbine buffer/spring with a fab defense GL Shock buttstock. It shoots amazing and I havent had any kind of feed or ejection issues but it ejecting spent cases in the 1-2:00 area.
So mu question is should I try a heavier spring or buffer for its dedicated lower??? It will be a 6 position carbine buffer tube and will have the same fad defense GL Shock buttstock.
The recoil is very manageable but I figured since Im gonna throw together a dedicated lower for it and it seems to be over gassed that maybe a heavier buffer and spring might straighten out the ejection location and maybe even tame a little more of the recoil.... Any ideas or suggestions? Thanks in advance
