R16MP5 Reflex Suppressor
Manual: MP5 Reflex Suppressor with Easy Bayonet Mount (TM)
Reflex suppressor or silencer R16MP5 for Heckler & Koch
Maschinenpistole 5 has a new quickly detachable Easy Bayonet Mount with a friction ring
against accidental loosening. The all steel Reflex suppressor is a long-lasting and almost
maintenance-free muffler of muzzle blast, flash hider and recoil compensator. Suppressor
is also used to protect the shooter from hearing loss, which is a common menace especially
among those using firearms by their profession. Standard Reflex Suppressors finish is
military grade parkerizing. Model R16MP5 extends only 143 mm forwards from the muzzle.
Reflex Suppressor is designed to withstand full-auto shooting with full power 9x19 mm Para cartridges. Reduction of shooting noise is considerable, but mechanical noise of firing cycle and bullet's flight noise (ballistic "crack") are impossible to eliminate by any suppressor. Flight noise of supersonic bullet is found to be useful in actual battle: Cracking sounds of bypassing bullets tends to bluff the enemy, and so hide the position of a shooter, as muzzle blasts, muzzle flashes and other shooting signatures are eliminated with a suppressor. Shooting noise with a suppressor and full-power 9x19 mm cartridges is about as loud as a .22 rifle with Super Speed cartridges.
If extra quieting is needed it may be necessary to use cartridges with reduced powder charge; so called subsonic loads with bullet velocity preferably less than 300 m/s. If commercial subsonic ammo is unavailable, any experienced handloader may develop and reload them. If the bullet weight is 8 g or less, these loads are unable to complete the feeding cycle of MP5 reliably. However, mechanical noise - other than snap of the hammer - will be absent, and suppressed muzzle blast is not much more audible. Manual ejection and feeding are quick and easy to accomplish. For extra quieting, Reflex Suppressor can also be used wet. If bullet weight is 9 g or more, it is possible to get reliable automatic feeding along with silent flight of the bullet. Mechanical noise of the action is, however, always present. Truly 'silenced' shooting with self-loading or full-auto firearms is possible just with limitations.
Mounting a suppressor with an Easy Bayonet Mount: H&K MP5 submachine gun has three bayonet lugs behind the muzzle. If lugs and muzzle are undamaged, unaltered and not badly worn, mounting is done easily without special skill or tooling. Slip the nut of the suppressor onto the muzzle and beyond the bayonet lugs. First turn the suppressor counter-clockwise a couple of turns to make sure the locking nut is opened enough to engage the lugs. Then rotate the suppressor clockwise. After 1/6 turns you should feel the lugs clutching in their slots inside the nut. Now just tighten it clockwise. You will feel some resistance. This is a safety feaure of the novel friction ring of the Easy Bayonet locking nut to prevent losing the nut from disconnected suppressor while transfer and to provide more security against suppressor getting loose on the muzzle. The friction ring is a standard 20x2 mm O-ring and it can easily be replaced to a disconnected nut if it is worn or lost. Caution: Do not overtighten the suppressor! Twist by one hand, not with tools. Overtightening will cause unnecessary wear of muzzle aligning surfaces and in worst case result in unaligned mounting. Never shoot with a loose suppressor, as this will cause the bullets grasp the baffles. Disconnecting: Turn the suppressor counterclockwise a couple of turns while pulling it forwards (towards the muzzle). Now the lugs can be uncluthched from their slots by pushing the suppressor towards the gun, then rotating the suppressor 1/6 turns counterclockwise and pulling it straight out of the muzzle.
Maintenance: Reflex Suppressor is practically maintenance-free device. Normal fouling of powder and primers do not have effect on its functioning. Loose solid impurities like powder kernels and carbon chips are easy to remove by brisk shaking while keeping the rear-end pointing downwards. After a shooting session it is advisable to remove the suppressor. This helps water condensed from powder gas to evaporate away. For storage, ordinary gun oil can be applied.
