Reviews & Ratings for DELTAC Muzzle Jam Nut — 6 reviews — Page 1

Works perfect for what I needed will need two wrench’s to instal

Jam nuts are the best things ever for installing and timing your muzzle devices. You just thread on a jam nut all the way to the shoulder. Then you thread your muzzle device on (and time it if necessary). Then you tighten the jam nut up against your muzzle device using two wrenches (one of them should be a torque wrench). That's it. Your muzzle device is mounted and timed. If the timing is off, you just have to loosen it and try again, but the jam nut is infinitely re-usable. You'll never have to deal with crush washers or shims again.

This one is is slightly thicker than others and it helped me to move my muzzle device just far enough forward that I can mount my blast cans/suppressors exactly at the end of the handguard. Before that they were inside the handguard enough to make it a pain in the butt to unlock and remove. This one was perfectly sized to work for this specific build. There are many sizes of jam nuts available, so find the sizes that work best for your build.

Was installing a surefire muzzle device so I could run my suppressor on a PSA AK. The shims provided did not provide enough offset to time the device correctly but this jam nut filed the gap perfectly and enabled me to time the muzzle device perfectly.

I needed this for my Krebs Custom core rifle. The build quality is top notch and fits perfectly on the rifle with Spikes Tactical muzzle brake. The black color is amazing and matches the rifle perfectly.

Needed a bit of a spacer for some long threads on an AK barrel to make the flash hider flush. This allowed me to protect and hide the threads that weren't capable of being under the flash hider. This did the trick.
