Several thousand rounds with no issues. I can't remember the weight its been 6 years or so. I could shave off another 3-7 ozs then add a lpvo that adds about 8-12ozs back on. There's metal inserts in the higher stress areas (buffer tube threads, takedowns and trigger pins). I been wanting to do a poly in ar10/lar308/sr25 type, but 2A (12-13oz set) at the time had beat the lower weight against the poly.Love it! How are you liking the poly receiver? That’s gotta be under 5-6 ounces right? Any issues?
My next goal is to do a 6 and under build, rifle + optic. I’ll definitely have to spend a bit more.
