The Revolution Fixed Barrel Spacer replaces the spring on Revolution silencers to lock the piston from traveling when the suppressor is used on a fixed barrel firearm. The spacer should only be used on a fixed barrel firearm. Additionally the piston with spring should only be used on non fixed barrel firearms as using a sprung silencer on a fixed barrel firearm will cause damage to the suppressor.

THE FIXED BARREL SPACER IS RATED UP TO .300BLK SUBSONIC. USE OF THIS PRODUCT ON SUPER SONIC, CENTERFIRE RIFLE CALIBERS WILL CAUSE DAMAGE TO THIS PART AND POSSIBLY THE SILENCER AND IS NOT COVERED UNDER WARRANTY.

Made of anodized 6061-T6 Aluminium.

These 3 Lug adapters are HK pattern and will work with any 3 lug silencer on the market made to this standard. They will also work with Griffin 3 lug interface assemblies

The 5/8x24 and 13.5x1mm LH versions have a cylindrical machined extension added to the mount. The 13.5mm version has flats for a wrench on that cylinder extension and has the O-ring interface typical of 13.5x1 LH mounts. The other 3 Lugs are the smaller version pictured.

The 5/8x24 is meant to provide a 3 Lug mount to 30 caliber barrels but is also compatible to 9mm barrels where that thread is uncommonly used. Most 30 caliber barrels are threaded 5/8x24 thread pitch.

Made from 17-4ph stainless and Melonite QPQ treated.

Models:
1/2x28 - 3L1228
1/2x36 - 3L1236
13.5x1 LH - 3L1351LH
5/8x24 - 3L5824

Fixed mounts allow you to remove the booster piston, spring, and piston retainer and replace with this single component to use on your fixed barrel firearms. Sprung pistons should not be used on a fixed barrel firearm as this will cause the booster assembly to batter itself to destruction. This part saves about an ounce of weight versus running a booster piston and fixed barrel spacer.

5/8x24 is a good fit to direct thread to 300BLK guns. 1/2x28 would work for 1/2x28 threaded 9mm carbines.

Made from 7075 T6 aluminium.
