Luth-AR BL-55 5.5" Flash Hider .223/5.56 1/2x28 - Manganese Phosphate

The Luth-AR BL-55 is a heavy-duty 5.5" flash hider designed for .223 Remington / 5.56 NATO AR-15 barrels. Machined from 4150 steel and finished in durable manganese phosphate, this robust muzzle device is built to deliver long service life in the field while taming muzzle flash in low-light conditions.

The BL-55 installs via a standard 1/2x28 right-hand thread pattern, making it a direct fit for the overwhelming majority of .223/5.56 AR-15 barrel installations. At an overall length of 5.5", a width of 0.877", and a weight of approximately 7.2 oz, the BL-55 adds substantial mass at the muzzle - shifting the rifle's balance forward and giving the front end a planted, steady feel.

The manganese phosphate coating provides a durable, low-glare surface that resists corrosion and wear through repeated use. The BL-55 ships not pre-drilled, allowing builders and end users to drill and pin it to spec for fixed-stock rifle configurations where a permanently attached muzzle device is required.
