CMMG RipBrace Standard Receiver Extension & Brace Kit - Black

The CMMG RipBrace Standard Receiver Extension & Brace Kit delivers a purpose-built pistol brace solution for AR-pattern builds that demand speed and simplicity. Built around CMMG's Fastback Technology, this full-size carbine-length brace deploys with a straight-back pull—no locking tabs, no fumbling, just clean extension when you need it. Whether you're setting up a dedicated pistol or want a modular brace that adapts to your shooting style, this kit arrives with everything needed for installation and tuning.

The ambidextrous design and lightweight polymer construction make the RipBrace equally at home across left and right-hand shooters. The included P3 Indexing Screw system (Personal Position Preset) lets you dial in a custom preset, so your brace returns to the same extended or collapsed position every deployment. That consistency matters on the range, in training, or when reliability counts.

This is a complete receiver extension and brace package—you're not hunting for separate components. The kit includes the standard RipBrace, a 6-position RipStock Enhanced tube, the P3 indexing hardware, spring, buffer, ambidextrous sling plate, and castle nut. Assembly-ready and designed to meet ATF compliance standards, it's built for builders who want proven engineering without overcomplication.

Frequently Asked Questions

What's included in the CMMG RipBrace Standard Kit?

The kit ships as a complete receiver extension and brace package: the standard RipBrace itself, a 6-position RipStock Enhanced receiver extension tube, a P3 indexing screw, spring, buffer, ambidextrous sling plate, and castle nut. You have everything needed for installation on a standard AR receiver.

How does the Fastback Technology work?

Instead of fighting locking tabs or lever mechanisms, the RipBrace extends and collapses with a straight-back pull. The design prioritizes speed and simplicity, with no binding points in the deploy cycle.

Can I customize the brace position?

Yes. The P3 (Personal Position Preset) indexing screw system lets you set a custom reference point, so your brace consistently returns to your preferred extended or collapsed setting without guesswork.

Is this kit suitable for left-handed shooters?

Yes. The ambidextrous functionality includes an ambidextrous sling plate and is designed to work equally well for both left and right-hand configurations.
