Hi, is the Blackthorne 50 BMG Caliber uppers for AR15 any good. are they made by vulcan? i have seen many reviews on staying away from there rifles but i dont seem to find anything thing about these 50 bmg uppers for the ar15 format. The massive bolt head is of a 2 lug design, with a 90 degree throw. i did hear the rifles with the 2 lug are bad. just checking before spending the money on one. Thanks in advance.
sorry i am new to the forum so it might take me awhile to get used to it.
