Leapers UTG PRO 1.2" outside-diameter AR-15 pistol receiver extension — the buffer tube that anchors your carbine buffer, action spring, and (for pistol builds) a pistol brace or bare buffer stack. Precision-machined from 7075-T6 aircraft-grade aluminum with a Type III Class II hard-coat anodized finish and a dry-film-lube-coated interior for smoother buffer cycling.

Specs & features:

• 1.2" outside diameter — pistol/bare-tube profile (not stock-body diameter)
• 7075-T6 aluminum, precision-machined
• Type III Class II hard-coat anodized, matte-black finish
• Dry-film-lube coated interior for smooth buffer travel
• Accepts standard AR-15 carbine-length buffers and action springs (sold separately)
• Fits standard AR-15 pistol lower receivers and end-plate stacks

Fitment: AR-15 pistol lower with a carbine-length buffer stack. This is a bare pistol tube — pair with a carbine buffer + action spring + end plate + castle nut to complete the build. Not for rifle-length tubes or AR-10 platforms. Verify your lower is threaded for a carbine-length extension before install.
