Questions & Answers
Will this work with 300blk? Expert Answer

For the .300BLK you would have to use the 9mm version, not the 5.56 version.

by Tom B, Gear Expert, October 11, 2021
Can this be used with a Ruger American Gen 2 rifle chambered in .223 rem (22" barrel)? Manufacturer Answer

If your .223 barrel has 1/2x28 thread pitch you can use the King Comp.

Great compensator by John C., May 17, 2020
It’s a great compensator. I bought this model specifically to work with the Strike Industries Oppressor. The compensator redirects the gasses nicely. Easy instillation and well built. Strike Industries makes good quality products.

This beauty is pure quality but do not buy this if you're wanting to put this on your Brigade AR9 (BM9) because it won't fit, it likely fits other AR9 models but doesn't fit the BM9 unfortunately. I will keep this though because the quality is phenom...

phenomenal break by Ed Flo, Verified Owner, May 12, 2021
I have this and the large sized break on a 9mm pcc and even a handgun. This works marvelously for muzzle rise, I even have the oppressor installed in the handgun set up and it definitely makes a huge difference. This is a must buy while you can

difficult install by KingRat, February 5, 2025
This should be shipped either with a selection of shims, or a locking nut. The supplied crush washer is really pointless. I would have had to turn an additional almost 3/4 of a turn after initial contact with the crush washer. I don't believe it had...

Product Info for Strike Industries Mini King Compensator

The Strike Industries Mini King Comp 9mm brings the proven performance of the full size King Comp in a more compact, lighter package designed exclusively for 9mm carbines. The Mini King Comp retains the full range of features of the King Comp in a single chamber format. The large single baffle captures the vented gasses for recoil mitigation. The redirection jets work to stabilize the muzzle end for faster follow up shots while dampening felt concussion on the shooter end to maintain the pleasant shooting characteristics of 9mm carbines. The end of the compensator features the crown of standoff/wire cutting tines that gives the compensator its name. While 9mm carbines are known for low recoil and fast handling characteristics, give yours an extra edge in performance with the SI Mini King Compimage
