Lancer Systems brought purpose-built .300 Blackout configurations to SHOT Show 2026, marking their first complete firearms chambered in anything other than 5.56. The company known for magazines and carbon fiber handguards built two L15 variants specifically for running .300 BLK with suppressors.
The key feature here is the Superlative Arms adjustable gas block that can vent excess gas when running suppressed. Both models come with Radian Raptor SD charging handles (optimized for suppressor use), Radian Talon ambi safeties, and Lancer's L15 lower with tactical magwell. The pistol gets a Law Tactical folding stock adapter and SBA5 brace while the rifle runs a B5 Bravo stock and BCM Gunfighter grip.
The 9-inch pistol uses a Faxon Match Series Gunner barrel with pistol-length gas and a 7.5-inch LCH5G2 handguard. Ships with one 20-round and one 30-round Lancer L5AWM .300 BLK magazine. MSRP is $2,499.99.
The 16-inch rifle gets a Rosco Bloodline barrel also running pistol-length gas (which is common for .300 BLK even on longer barrels) and a 13-inch LCH5G2 handguard. Ships with one 10-round and one 30-round magazine. MSRP is $2,199.99.
Lancer Systems L15 .300 Blackout Specs:
The pricing puts these squarely in the premium category, but that's expected given the component list. Radian charging handles alone run $90+, and the Superlative Arms gas blocks aren't cheap either. The question is whether Lancer's carbon fiber handguards and proprietary L15 lower justify the price over just building your own .300 BLK with similar parts.
What do you guys and gals think? Is there enough here to justify buying complete, or would you rather spec your own .300 BLK build? Let us know your thoughts in the Comments below! We always appreciate your feedback.
