The Tuna Cans 5.56 XL and WRMFZY 5.56 are full-size 5.56 silencers that use conventional technology to produce competitive pure muzzle blast suppression.  Both silencers are stainless steel, with the XL model possessing a modular baffle array and the WRMFZY silencer being 3D-printed, larger diameter, and shorter. The technology in the silencers is well studied; it offers scalable pure suppression performance with high back pressure and pronounced FRP.  These budget-friendly silencers, if used with reciprocating weapon systems, dictate the use of weapon tuning such that ejection port blast hazards may be reduced.

In this review, the Tuna Cans 5.56 XL and WRMFZY 5.56 performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a commonly fielded gas-operated rifle, which is an incredibly difficult task. How would the Tuna Cans 5.56 XL and WRMFZY 5.56 perform on your M4 with a 14.5-in barrel?
