M16 / M4 sound suppressors

M16 / M4 / AR15 sound suppressors.

The SAI suppressors for M16 / M4 / AR15 type riffles are all made for easy mounting on existing M16A2 muzzle compensators or flash hiders. The M16A2 type sound suppressors are designed especially for use with full-power service 5.56 x 45 mm / .223 caliber cartridges.

A standard SAI M80-K model sound suppressor extends the M16A2 flash hider with approx. 132mm (5.2 inches). Slightly longer versions, optimized for increased sound attenuation, extends weapon with approx. 152 mm (5.98 inches).Also short suppressors for M4 type carbine rifles are in production.

Adding a sound suppressor to a M16 / M4 (or other AR15 type 5.56. rifles or carbines) will give the shooter a feeling of being able to control the rifle with much more ease, as the suppressor has very good muzzle brake and compensator effect.

A standard .223 Rem bullet is characterized with having a relative low flight noise level. This - and the fact that standard powder levels in the bullet are somewhat moderate – makes the .223 assault rifles relative easy to suppress to safe levels. When the M16 rifle is suppresses more dirt will however find its way back into the rifle. Thus the receiver, magazines etc. will get dirtier when shooting suppressed. The slightly increased back gas pressure will also cause the sound levels from the ejection port to increase. The SAI suppressors for M16 5.56mm rifles are designed to minimize the negative effects of an increased back gas pressure.

A sound suppressor for M16 / M4 rifles is not able to eliminate the report from the shoot completely. Noise from the ejection port and from the bullet is normally the main source of noise on a suppressed M16. Optimizing for the lowest possible report thus includes not only a soft brass catcher but also special loaded 5.56 x 45 mm subsonic rounds with velocity around 300m/s (1000 fps).

Using standard ammunitions however is completely safe and also has some advantages, as the bullet flight noise will make it more difficult to locate the shooter as origin of this sound is difficult to pin point and because the bullet flight noise is louder the noises origination from the suppressed rifle.

A special characteristic of the SAI M80 suppressors is its ability to decrease the natural bullet-spread of the 5.56 rifles. The SAI M80 5.56 sound suppressors are designed with symmetrical baffles and symmetrical mounting to ensure optimal precision of the M16 / M4 rifles. There is a slight compromise of sound attenuation effect by doing so (1-2 db), but close co-operation with military end users and rigorous testing has proved that precision – and other characteristics – is preferred above sound levels. The increased precision is even more evident when using the very short M80 CQS (close quarter suppressor) on short barrel carbine riffles - like the Colt Canada C8 or the Colt M4.

SAI 5.56mm suppressors for M16A2 compensator mounting is virtually maintenance free. Normal fouling of the suppressors from powder and primers has no effect on the function. Using compressed air for standard cleaning is advised. Lifetime warranty with service agreement is an option.
