Good Quality Item
I had recently purchased a muzzle break from Optics Planet and was having trouble getting it aligned properly using a standard crush washer. I decided to order the Tacfire muzzle break jam nut to correct the problem. The jam nut was a good quality item. It was just the perfect thickness to lock the new muzzle break in place at the correct position. I will use the jam nuts in the future for two reasons the first is that it only takes a second to get the timing correct and the second is they are reusable.
AR10 Jam Nut
This jam nut Worked exactly as I had hoped. The threads were cut to specifications and screwed on smoothly , the wrench size is 3/4". There is not much you can say about a jam nut but optics planet wants you to write a book in the reviews. It made clocking the muzzle device easy.
Pros:
- Easy to install
Cons:
- None
Best Used for:
- threaded muzzle
Would recommend: Yes
Muzzle brake installation where shims won't work.
I used this jam nut to install a Yankee Hill muzzle brake on my T/C Compass which did not have a sufficient shoulder for timing with shims. I was afraid that I would not be able to use the YHM Resonator R2 silencer/suppressor with my T/C Compass .308 because the Quick Disconnect muzzle brake that came with it requires shims to time it correctly. I heard that I can also use a jam nut rather than the shims, so I purchased this one from Optics planet and it works perfectly. The only drawback is that it was so expensive.
Pros:
- fit, finish, function
Cons:
- outrageously expensive for what it is
Best Used for:
- timing muzzle brake on shoulderless barrel
Would recommend: Yes
perfect fit
Exactly what I needed to ger my compensator where it needed to be. Before my I couldn’t get compensator where it needed to be without risking harm to my rifle....this was the perfect add on! And can’t beat the price rather than a whole new compensator. Easy fix
Pros:
- Durability
- easy to install
Cons:
- None
Best Used for:
- muzzle devices
Would recommend: Yes
