The JRC Gen3 Rifle .45 ACP 17-inch Threaded 13+1 Glock Mag is a semi-automatic pistol-caliber carbine built for reliable range fun, training, and compact home defense. It uses a straight blowback action and accepts Glock-compatible magazines, making it a natural companion for your Glock .45 pistol. The 17-inch threaded barrel and free-float M-LOK forend give you accuracy and accessory options right out of the box.

Key Features
- Ambidextrous Bolt with Reversible Ejection — You can configure the bolt for left- or right-hand ejection in minutes, so lefty shooters or family members can shoot without brass bouncing off their face. That means safer, more comfortable training for everyone.
- Free-Floating M-LOK Forend — Attach a light, laser, or vertical grip exactly where you need it without affecting barrel harmonics. It keeps your support hand cool and your accessories stable.
- 17-Inch Threaded Barrel (5/8×24) — Add a suppressor, muzzle brake, or compensator to reduce recoil or noise. The longer barrel also gives you a sight radius advantage for more precise shots at the range.
- Straight Blowback Action — Simple, reliable, and easy to clean. No gas system to tune or foul, which means more time shooting and less time wrenching. Perfect for new shooters learning the basics.
- Glock Magazine Compatibility — Use the same 13-round (or larger) Glock .45 mags you already own. This cuts down on gear duplication and makes range bag packing simpler for the whole family.
Who It’s For
This carbine is built for families, youth shooters, and beginners who want a .45 ACP PCC that’s easy to shoot, easy to maintain, and easy to share. It’s also a smart choice for anyone who already owns a Glock .45 and wants a home-defense carbine that uses the same magazines.
Pros / Cons
- Pro: Ambidextrous design makes it a true family-friendly rifle — lefties and righties can shoot it without mods.
- Pro: Threaded barrel opens up suppressor use, which is great for hearing-safe training for kids and new shooters.
- Pro: Glock mag compatibility means you can share mags with your pistol — fewer parts to track.
- Con: The straight blowback system creates more felt recoil than a gas-operated PCC, so younger or smaller shooters may need extra practice to stay on target.

FAQ
Can I use standard Glock 21 magazines with this carbine?
Yes. The JRC Gen3 is designed to accept Glock .45 ACP magazines, including factory Glock 21 (13-round) and extended magazines. The included 13-round mag works perfectly.
Is this carbine suppressor-ready out of the box?
Yes. The 17-inch barrel is threaded 5/8×24, which is a common suppressor mount thread. You’ll need a compatible suppressor and possibly a Nielsen device for reliable cycling.
How do I switch the ejection side for left-handed shooting?
Remove the bolt, flip the ejector block to the opposite side, and reinstall the bolt. The process takes about five minutes with basic tools. Full instructions are included in the manual.
What is the warranty on this carbine?
JRC offers a limited lifetime warranty on the receiver and a one-year warranty on all other components. Contact their support for details.
Will this carbine fit in a standard rifle safe?
Yes. With a 17-inch barrel and collapsible stock, the overall length is approximately 32 inches collapsed, making it suitable for most rifle safes and cases.
