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.

Can this be used with a Ruger American Gen 2 rifle chambered in .223 rem (22" barrel)? Manufacturer Answer

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.

Quality Compensator but does NOT fit Brigade BM9 Threads! by Harvey M1, Verified Owner, November 14, 2021

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 .223/5.56 brings the proven performance of the full-size King Comp in a more compact, lighter package designed for the .223/ 5.56 caliber. The Mini King Comp retains the full range of features of the King Comp but in a single chamber format. The large single baffle captures the vented gasses, producing a net force forward of the shooter that helps mitigate recoil. The ports work to stabilize the muzzle end for faster follow-up shots while dampening felt recoil on the shooter to maintain a pleasant overall shooting experience. The end of the Mini KING comp features the crown of standoff tines that gives the compensator its name. While .223/5.56 carbines are known for low recoil and ease of weapon manipulation, you can still find an edge in performance with the Strike Industries Mini King Comp.
