BROWNELLS AR-15 9MM BOLT CARRIER GROUP

The BROWNELLS AR-15 9MM BOLT CARRIER GROUP is Brownells latest entry in their own branded AR-15 parts. In the super competitive aftermarket AR-15 parts and accessories world Im glad to see them step up their game and branching out beyond magazines, barrels and flash hiders. A Brownells branded 9MM AR bolt carrier is a safe bet for your 9MM carbine.

BROWNELLS 9MM AR BOLT CARRIER GROUP

The Brownells 9mm AR-15 Bolt Carrier Group is specifically designed for use in pistol-caliber carbines, which are a growing trend in the AR-15 world. This bolt-carrier group allows AR builders to custom-make their own 9mm AR.

The Brownells 9mm AR-15 Bolt Carrier Group is constructed entirely from a single piece of steel billet and features a pinned weight that can be taken out for compatibility with different buffer systems.

  • Compatible with both Glock and Colt magazines
  • Features complete nitride treatment for reduced friction
  • Integral gas key eliminates issues with loose gas-key screws

The Brownells 9mm AR-15 Bolt Carrier Group also features a captured firing pin in order to prevent the possibility of slam fires.

ORION 9mm AR-15

It always excites me to learn of new players and products in the field of AR-15 rifles, carbines and pistols. The latest to catch my interest is the Orion 9mm AR-15 product lineup. It’s common knowledge here on AR-15 TACTICAL that I completely embrace pistol caliber AR-15 carbines, especially those chambered in 9mm.

The 9mm cartridge  is standard issue to many law enforcement for use with duty sidearms, the United States Military M9 pistol and probably the most popular centerfire pistol cartridge in the world. This commonality guarantees easy to locate and inexpensive ammunition for shooters everywhere.

ORION 9mm AR-15 Product Lineup

Orion Guns offers a full line of 9mm AR-15 products that include complete 9mm AR-15 rifles, complete 9mm AR-15 upper receivers, complete and stripped 9mm AR-15 lower receivers and 9mm AR-15 barrels. What is not clear about Orion Guns is whether they actually manufacture any 9mm AR-15 hardware themselves or assemble hardware from other manufacturers. I suspect the answer is somewhere in the middle. The pictures on the Orion Guns website as well as the website appear to be home brew.

Judging from the pictures on the website I suspect Orion is producing 9mm AR barrels and combining them with hardware from other manufacturers as necessary. Nothing wrong with any of this. In fact I praise and encourage them for recognizing a void and diving in. Orion Guns must be doing something right because I learned of them from Brownells. Click here for more information and ordering.

ORION 9mm AR-15 Barrels

The Orion AR-15 Barrels Chambered in 9mm are available in 5″, 8″, 10.5″ & 16″. Made of 4140 Chrome Moly Steel and black nitride finished, these barrels are heat treated and stress relieved. They are stress relieved once again after the button rifling process. All barrels threaded 5/8-24 with a 1-10 twist.

ORION 9mm Lower Receivers

The Orion 9mm lowers appear to be assembled to a price point. My preference would be a Hahn 9mm magazine block and KNS anti-rotation pins installed on the lower. Note use the KNS anti-rotation pins on all 9mm AR rifles. Visit our 9mm rifle project that closely resembles the Orion offerings

JP JPBC-9MMA JP Enhanced 9mm AR15 BOLT CARRIER GROUP

JP JPBC-9MMA JP Enhanced 9mm AR15 BOLT CARRIER GROUP is machined to the same exacting tolerances as our bolt carriers, this second generation 9mm bolt assembly is an entirely new design that eliminates the need for a central mass (slug) to readily function with our 9mm JP Silent Captured Spring without compromising bolt weight and reliability. In fact, when combined with our JPSCS-9MM, you have the heaviest, most reliable 9mm operating system that dramatically reduces bolt bounce while improving accuracy.

This bolt assembly is .9 oz. heavier than the Rock River Arms 9mm bolt with its central mass removed. When used in conjunction with the Silent Captured Spring, the complete JP 9mm operating system is slightly heavier than the complete RRA bolt and buffer, some of the bolt mass having been transferred to the SCS in our system.

JP JPBC-9MMA JP Enhanced 9mm AR15 BOLT CARRIER GROUP  Features

Reduced stroke length for faster firing impulse when used with JPSCS-9MM
Designed for optimal function with JPSCS-9MM for a heavier operating system that reduces bolt bounce while improving reliability and accuracy
Tighter firing pin channel to reduce pin wear
High-energy tumble process offers a finer cosmetic finish
Includes firing pin and retainer pin

JP JPBC-9MMA JP Enhanced 9mm AR15 BOLT CARRIER GROUP  Compatibility
