5 of 5 Underrated Company with exception quality. February 16, 2024
: Chris A. from GA  
I bought my first upper from yall in 2018 and I remember receiving it in two days. It was a 16” barrel with 12 in quad rail.

Solid rifle. I am not gentle with it at all. Yet it eats every type of round I put through it.  Wish I could submit a pic
