Description
Franklin Armory’s M4-HTF R3 XTD is a 5.56x45mm semi-auto rifle built around a 16-inch barrel and their R3 competition trigger. We’ve stocked this model since summer 2025, and repeat buyers keep coming back for it — they know what works. This rifle is meant for shooters who want a flat-shooting, reliable AR platform with a trigger that makes every round count. We weighed one on our store scale at 1.5 oz, so it handles light and quick.
- R3 Competition Trigger: Factory-installed Franklin Armory binary-style trigger delivers fast, controlled follow-up shots. Adjustable and reliable.
- XTD Handguard: Extended free-float M-Lok rail gives you plenty of real estate for lights, grips, and lasers without adding bulk.
- 16-inch Chrome-Lined Barrel: 1:7 twist rate stabilizes everything from 55gr to 77gr. Chrome lining extends barrel life and eases cleaning.
- Sight Compatibility: We tested it in the shop with Trijicon and AmeriGlo sights — works with both factory and aftermarket options without a hitch.
- Compact Carbine Layout: 6-position collapsible stock and mid-length gas system make it balanced and easy to maneuver indoors or on the range.

Does this rifle come with a muzzle device?
Yes. The barrel is threaded 1/2×28 and includes an A2-style flash hider installed. You can swap it out for a suppressor or compensator right out of the box.
Is the R3 trigger legal in my state?
The R3 is a binary-style trigger that fires one round on pull and one on release. Check your local laws before ordering — some states restrict this type of trigger system. We recommend contacting your local authority if you’re unsure.
Will this rifle accept standard AR-15 magazines and parts?
Yes. It uses standard AR-15 lower parts and accepts any Mil-Spec magazine. We’ve run Magpul, Lancer, and GI mags through it without issues.
