The Spark rimfire silencer is Liberty Precision Machine’s first entrance into the silencer market. Anyone can build a moderately quiet rimfire silencer, but to really distinguish oneself from the rest of the market requires a lot of effort, patience, and testing. After countless hours of research and development, we have finally developed a rimfire silencer that meets our high and exacting standards-one that we are proud to put our name on.

Unwilling to compromise, we set out to design a strong, lightweight, easy to clean, and most importantly, insanely quiet silencer. At a compact 5.35″ in length and a lightweight 4.8 ounces, the Spark provides class leading performance in a short and lightweight package. If it wasn’t the best on the market, we would refuse to make it. 

A proprietary baffle stack, engineered with poka-yoke design principles, creates a non-symmetrical 3 lobe seal geometry between the baffles that allows for easy disassembly, cleaning, and reassembly-ensuring the baffle stack will go back together correctly every time. The unique baffle design provides a deep tone that is extremely pleasant to the human ear. The use of a titanium tube, titanium end caps, and 17-4 PH stainless steel baffles provides an optimal balance between weight, strength, and ease of cleaning.
