Hi, any word or comment on the new style flash hider on the 09 model Swiss Arms CQB (552)?
The three prong flash hider will always have the end of the thread showing because it doesn't have a ledge stop nor requires a washer. You're asking Swiss Arms for something they don't make.
MPI can you post pics of yours that does not show these threads?
The HALO was designed to meet specific international military requirements for a compact, high efficiency suppressor for the 5.56mm weapons utilizing NATO ball ammunition. The additional requirement was that the suppressor be able to quickly attach securely to a 22 mm standard NATO specification flash hider without the use of tools. The HALO suppressor meets and exceeds these requirements in a physically small package.
The HALO utilizes the proven baffle design from the well known and highly successful M4-96D and is manufactured on the latest state-of-the-art CNC manufacturing centers from space age materials. It provides sound reduction well in excess of OSHA and MIL-STD requirements in a physically compact package. Additionally, there is no degradation of weapon accuracy. Suppressor life is known to exceed 25,000 rounds.
The patented mounting system utilizes the 22 mm standard NATO-specification bird-cage type flash hider as used by the military worldwide. Mounting or removal can be performed without the use of tools in less than 30 seconds. Because the mount uses the flash hider, it is necessary that the flash hider be concentric with the bore. Some of the AR15/M16 series weapons may have had the flash hider mounted with a split-ring lockwasher or a crush washer. The split-ring lockwasher will not keep the flash hider concentric and must be remounted. The newer crush washer may or may not keep the flash hider aligned properly, and we recommend re-mounting the flash hider with the provided peel washer. This suppressor and mount were designed specifically for military weapons and may not fit on non-standard aftermarket flash hiders or muzzle brakes often found in the United States. If there is any question, it is fairly simple to change to a 22 mm NATO specification flash hider, such as the Colt A2.
The suppressor comes with detailed instructions for installation and use. It also includes a peel washer for remounting of the AR15/M16 flash hider should the original flash hider be mounted with either a split-ring lockwasher or a crush washer.
The SIG 551 delivered in the United States has an integral flash hider 21.5mm in diameter, which is not NATO spec. On special order, we can provide a variant of the HALO specifically for this weapon. Although the SIG 552 also uses a non-specification flash hider, this flash hider is threaded on and we suggest changing the flash hider to one that is 22 mm in diameter.
