Best AR 7.62x39 build kit. Radical Firearms is AMAZING!

by -

This is the best pre built AR 7.62x39 conversion rifle you can buy for less than $500. It has NO light primer strikes and feeds perfectly with any mags (I'm using ASC and D&H Tactical mags) if your mag doesn't feed smoothly, put some clp on the follower and spring. Be AMAZED as it eats steel cased (Tulammo, Red Army Standard) all day long. Only time it wouldnt fire was when I came across a dud. (I re-fired it 3 times and nothing, so it was a dud) I am in love with this rifle. I wanted a MK-47 but they're to expensive. This is (w/o being able to use AK mags) like a Windham Weaponry in the AR firing 7.62x39 talent show!

It's running fine!


This kit is a great value with the upgraded stock, slim mlok rail, and brake. It's been running good so far no issues ~300+rds. I did add a heavy hammer spring (from brownells) and use RZE multi mags.
