CMMG Pistol Tube Assembly Features The CMMG Pistol Tube Assembly replaces an AR pistol s adjustable position buffer tube with a smooth sided pistol tube a change often needed when converting a rifle configuration into a true AR pistol build. Because the kit is designed to reuse the existing buffer spring and castle nut the overall cost and complexity of the conversion stays low compared to buying an entirely new buffer system. The included ambidextrous sling receiver end plate gives the finished build a usable sling mounting point regardless of which side a shooter prefers to attach their sling. This end plate also helps retain the castle nut properly once everything is torqued down. Finished in black to match most AR pattern builds the Pistol Tube Assembly integrates cleanly with the rest of a pistol s furniture without standing out. Because it is purpose built for AR platform pistols the parts are sized and threaded to match standard AR buffer tube specifications simplifying installation for anyone comfortable with basic AR armoring. This kit is a practical option for builders finishing an AR pistol project who need the smooth tube required for a brace or similar accessory rather than an adjustable stock tube. For AR pistol owners looking for a straightforward affordable way to complete their buffer tube setup the CMMG kit covers the essentials.
