For some reason, I am on this crazy quest to find a USGI, 20", A1 profile (PENCIL), 1:7 twist barrel, excellent condition. I know these exist; Colt or FN made some for the IDF, and a few made thier way to the civilian market. The most I really want to pay is $250, pure pipe dream, I know. I have a slab side M16 clone (all AR inside) and want the 1:7 twist barrel so I am not limited to M193 ammo, or the like. Anyway, if anyone knows of a lead, please let me know.
