LA Innovations “Prism” Aluminum Upper for M4

The LA Innovations Prism Aluminum Upper + Tensioner is the ultimate upgrade for competitive airsoft. We engineered this upper to be both lightweight and durable, while having features that no other upper has. The built in hopup tensioner allows for quick changes of handguard and outer barrels without having to take off the upper itself. The large cutout ports on both sides of the upper allow for quick hopup adjustments mid battle.

The tensioner is designed with inner o rings to stabilize your hopup unit and inner barrel. The picatinny rails sit right above the top of standard V2 gearboxes, ensuring a very low sight profile. Matched with the LA Innovations handguard, the front sight perfectly sits between the rails for a beautiful sight picture. We have truly designed the next wave of competitive rifles, with both top notch engineering, machining, materials, and finishing.
