A sound moderator will set you back $200 in transfer tax and put you on a Federal database. If all you want to do is make your 5.56mm/.223 AR more pleasant to shoot and reduce muzzle flip and felt recoil, the Levang Linear Comp is the way to go. It significantly reduces noise at the shooter’s end and is less noisy than a USGI flash hider to shooters at either side of you. Many comps make life unpleasant for adjacent shooters and will make you unpopular at the range. The Levang AR Comp pushes all the noise and blast forward, away from your ears. The unit employs a large expansion chamber ported to the front.
SPECS: Material: Matte blue steel finish. Length: 2-1/8″ (5.3cm), Diameter .971″ (24.6mm). Thread: ½”-28 tpi. Only suitable for 5.56mm/.223 caliber.
