Osprey Defense OPS-416 Gas Piston Kit
The Osprey Defense OPS-416 Gas Piston Kit offers a drop-in upgrade for AR-15s, converting from Direct Impingement (DI) to a short-stroke gas piston system. This conversion significantly reduces receiver fouling and heat buildup, improving reliability, especially in wet conditions. The kit features a tapered bolt carrier to mitigate 'carrier tilt' and is compatible with specific handguards like the Midwest Industries MCTAR-17G2. Testing showed reliable cycling with various ammunition, including Wolf .223, and effective operation with suppressors without manual adjustment.
