I'll second that, I work with Alex in his "other job" and he is a great guy who knows his way around a rifle! His place is kinda off the beaten path, but he'll take good care of ya!
And he actually lives off of 16 south (south of 1604) and closer to Poteet, but his address is Von Ormy...and here is his web site:
Dreadnaught Industries
Tell him 'M2' said 'hi!'
Cheers! M2
p.s. Are you military? If so, where are you stationed in SA?
Steve Cline 674-1111 or Felix Sotello (Dale Wise Guns) 734-9999 have both threaded barrels for me and have done a fine job.
