UTG PRO AR Pistol Receiver Extension Tube - Matte Black

The UTG PRO AR Pistol Receiver Extension Tube is a precision-engineered buffer tube built for AR-15 pistols that demand reliable performance without compromise. Made in the USA from 7075-T6 aircraft-grade aluminum, this receiver extension delivers the durability and consistency you need whether you're running a short-barreled pistol for home defense, range work, or specialized builds. The 1.2" outside diameter fits standard AR-15 pistol platforms, and the Type III Class II hard-coat anodized finish in matte black resists wear while keeping a professional, no-nonsense look.

What sets this tube apart is the attention to detail in its construction. The interior features a dry film lube coating that promotes smoother, more reliable cycling—reducing friction and wear over thousands of rounds. This means your buffer and spring interaction stays consistent shot after shot, cycle after cycle. The tube accepts standard AR-15 carbine-type buffers and springs (sold separately), so you can tune the action to your specific needs and platform weight.

Whether you're building a pistol upper, tuning an existing platform, or replacing a worn tube, the UTG PRO extension is a no-nonsense choice backed by American manufacturing standards. The matte finish hides dust and carbon better than polished surfaces, and the precision machining means zero fitment headaches during assembly.

Frequently Asked Questions

Will this AR pistol buffer tube work with my AR-15 pistol upper?

Yes. The UTG PRO receiver extension is designed for AR-15 pistol platforms and accepts standard AR-15 carbine-type buffers and springs, making it compatible with most modern AR pistol builds. Buffers and springs are sold separately.

What buffers and springs does this tube accept?

The tube is compatible with standard AR-15 carbine-type buffers and springs. These are widely available and allow you to customize the action tune to your specific build and needs.

Is the interior dry film lube coating permanent?

The dry film lube is applied during manufacturing and promotes smoother cycling and reduced internal friction. Over time and with heavy use, additional lubrication may be needed as part of routine maintenance, but the coating helps establish reliable, consistent operation right out of the box.

Why is the matte black finish better than polished?

The Type III Class II hard-coat anodized matte finish is more durable than polished surfaces and hides dust, carbon fouling, and minor wear better than shiny finishes—practical for a working AR pistol that will see regular use.
