In addition, the law banned all semiautomatic weapons that are equipped with a detachable magazine and two or more of the following bayonet lug, flash suppressor, protruding pistol grip, folding stock, or threaded muzzle. Magazines that hold more than 10 rounds are also prohibited. Weapons and magazines manufactured before September 13, 1994, however, are exempt.

A flash suppressor, however, can incorporate features that reduce the intensity of the noise. If this type muzzle device can be developed to the point where both flash, and noise can be reduced to acceptable limits, two knotty problems become solved siniultaneousiy. A large amount of effort has been expended on flash suppressors considerably less on noise inhibitors. A measure of success has been achieved in the suppression of noise thru exptn. No general design procedures, either theoretical or empiri-... 

A measure of success has been achieved in the suppression of noise but usually as a by-product of the development of another type of muzzle device, such as a flash suppressor General Requirements. Noise is an inherent characteristic of a gun and is usually associated with three main producers the projectile, the muzzle, and the gun components other than the muzzle. The noises produced by the gun components are mostly mechanical such as the sounds of moving parts, impact, and vibration. The projectile noises are mainly those caused by air turbulence following the projectile and the supersonic shock wave or ballistic crack generated by the projectile nose. Muzzle noises are produced by the air pressure build-up in the tube ahead of the projectile and by the proplnt gases issuing from the muzzle after the projectile passage...

The following material will enable you to construct a noise and flash suppressor (silencer) based on the Sionic 5.56 mm/M 16-unit designed and produced by MAC in 1972. 

Two distinct procedures may be used. The preferred method is to use a large thread cutting lathe, or a lathe and V x28 EF (Extra Fine)Die to turn down and thread muzzle to specs given in fig.3. This will duplicate the Colt M-16/AR-15 and Armalite AR 18/AR 180 muzzle dimensions. The %x28 pattern will allow installation of the Sionics Suppressors and other accessories available for the above guns. Maximum allowable misalignment of threads to bore axis 1 so it may prove a wise move to farm out the job to a competent machin-ist/gunsmith. No need to mention the suppressor, you only want to mount an M-16 flash hider. 

SECTION TWO - Purpose of Noise>and Flash Suppressor Assembly. 

The sniper in the field must take all possible care to avoid the compromising of his position to the enemy. Obviously, an advantage in his favor would be the suppression of flash and muzzle noise to eliminate the enemy from picking up the source of fire. The 5.56 mm suppressor is a device designed to deceive persons forward of the firer as to the exact location of the weapon and its operator. 

Although the suppressor will eliminate muzzle blast noise,flash and smoke, a super sonic crack will be heard when standard 5.56 NATO or commercial. 223 ammo is used. If special circumstances dictate maximum sound control and allow for reduced range and stopping power,the crack can be eliminated by firing specially loaded subsonic rounds. 

Virtually all smoke and flash is retained wi thin the launcher.The small amount that does escape through the hole in the front piston, is diffused by the flash suppressor.The suppressor also serves as a protective cover for the nose of the projectile. 

In the mouse muscle nicotinic receptor (nAChR), NB-tyrosine was incorporated at positions 93 and 198 of the a subunit. These are conserved residues crucial for acetylcholine binding. The mutagenized mRNA and the relative nonsense suppressor tRNA charged with the NB-Tyr were injected into Xenopus oocytes. The channel was successfully expressed and incorporated into the egg membrane [116]. In the following voltage-clamp study, a train of about 20 near-UV laser pulses (300-350 nm) was able to increase acetylcholine-induced conductance across the membrane with about 5% of decaged Tyr residues in any one flash.
