NEW TRUE- FITTING SEALS! Color may be different due to material availability at time of machining. High-quality breach seals are made from a non-burning material, yet flexible and durable to retain its sealing integrity and long life. The seals construction combines two necessary features required in any good sealing application. Elasticity to cover well over surface imperfections impeding any blow-by of air, and a tough sub-straight to hold radial shift to a minimum staying perpendicular flat to surface during burst force. These two key elements retain pressure bang on, straight-away down the barrel! A precise, new robust seal designed exclusively to inhibit any pressure loss! Radial machined corners to eaily locate allowing a very EZ install of both seal and projectile. olika färger
