I already have a Colt 723 "style" build that I really like. It's of the later Larry Vickers type with an M4 profile barrel in 14.5. Actually it's a Colt SOCOM barrel but it looks like a M4 profile on the bits one can see... It's what I had and I like it. Picked up another upper so maybe a early style with a pencil barrel? Who makes a quality 14.5/7" skinny barrel, carbine with front sight tower? Or maybe a rifle upper?
Thanks
