I recently purchased this gun off gb to get in the grendel game. The prior owner states it was an adams arms barrel, but i can find no info that adams ever produced a grendel barrel. Its a 20 inch barrel and the only mark i see us an 8 just forward of the barrel nut. The end of the barrel has a few grooves but i havent gotten to aggresive to see if its a thread cap or not. Any ideas?
