marriedwchildren256 See Title line... I screwed up and got a MBA-1 Rifle Butt stock. NGL though I don't really like it. It's completely plastic and I really wanted something with a bit more of a recoil pad (along with a cheek rest).
11C1P marriedwchildren256 Yes. The tube, detent & detent spring are all interchangeable. You can also use the A2 spacer & butt stock. Most of the LPK is interchangeable, the mag release is different though. Also the pivot & take down pins are different.
hoffmantactical A rifle tube will work, but the lower must be printed with the use of the counterbore block as a negative body. It's under the heading of "cut rifle tube".
