Intended uses-

While it may work on other applications the SD-1 is designed for a 16" barrel with a Carbine length gas system. On a 22LR or a 9mm they can be used on any length barrel down to 10". 

Example would be a 16" barrel with a YHM Specter length rail system or one of our Spikes lightweight rails in the 9" version.

Method of Attachment-

The SD-1 shrouds back over the barrel adding no length to the barrel.

Appearance-

With the SD-1 installed back into your rail system your 16" rifle will have the appearance of an SD suppressed rifle.

Thread pitch-

1/2 x 28

Length-

6.75"

Diameter-

1.50"

Weight-

6 oz.

Make sure your rail or free float tube has enough clearence for the SD-1 to fit inside.

Material-

These cans are CNC machined from 6061 aluminum.

Finish-

Anodized Flat black.

Please Note-

THESE ARE ONLY FOR LOOKS. IT IN NO WAY MAKES THE WEAPON MORE QUIET  - NO STAMP NEEDED.

General rule on threads-

Most Production barrels for 223/5.56 would be 1/2x28, needing a -1 Fake Can,

Most Production barrels for 9mm (ie. Colt, RRA etc.) would be 1/2x36, needing a -2 Fake Can. There have been a number of other calibers also done in 1/2x36.

This is ONLY a general rule, not a hard and fast rule, we do not guarantee your threads will fall under this rule, it is for guidance only.
