I'm looking at purchasing 7.62 and have narrowed my choices…So I hope. I've narrowed to Larue OBR 7.62, Super SASS, LWRC REPR, and GAP 10. I'm hoping to keep price down, but with this group I'm not sure possible. The GAP site gives very little on info and how to make or buy mods other that the price and/or if any other mods are available. Love the Larue, it's on costly side of the bunch. Right now because of price I'm leaning toward the Super SAS. Would appreciate all technical and personal feedback. Thanks. Oh, and would prefer 20" barrel.
