I'll take this
#1. Complete M4 stock assembly with H buffer. Comes with milspec stock body, 5 position milspec diameter tube, end plate, castle nut, H buffer and action spring. Unsure on maker of tube, but it is milspec diameter. The stock body is also milspec diameter, and I am 99% sure it is BCM. This is used, but in good condition. The body was neatly pinned to the tube, by the previous owner, dealer, or 'smith, by means of a small roll pin, which has been removed, to unpin the stock. It could be re-pinned if buyer wishes, and I can include the pin, if requested. Stock functions fine, and you can't see the hole in the tube, unless you remove the body from the tube. The hole in the body is only visible from the left side, and isn't very noticeable unless you look for it. See pics. $55 shipped via Priority Mail.
