This product again for me was a little difficult to install. The right tools are a must and basic AR15/ M4 gunsmithing knowledge is a benefit. The J Comp is manufactured with 6 ports directing gases away reducing muzzle jump. Made of steel. On the Range it seemed there was a slight reduction in muzzle jump and follow-up shots seemed easier to stay on target. A2 flash suppressor had a washer installed as this product did not. Loctite might benefit well. Clean up was easy with usual cleaning supplies and all areas could be easily cleaned

First out of the box the J-Comp is well put together. The craftsmanship is top notch and it feels sturdy in your hands. The design is unique and thought out. One negative on the design is that it a little bit longer than the other muzzle devices out on the market. I don’t believe it is that negative of an issue though.

I was disappointed that there were no directions with the product. It came in the box and that was it. If they were to add directions and some loctite to the packaging it would take care of that problem.

I was impressed with the performance of the product. I could tell the difference in the recoil of my rifle with the J-Comp installed. The recoil was less and it was easier to stay on target when taking multiple shots. I felt I was in control of the rifle at all times. I did not feel it pull in any direction.

The flash suppression with the J-Comp was superb. I could really tell the difference.

The J-Comp is a very impressive product and at the price I think it is a great buy if you want to reduce the recoil and flash on your rifle.

The Strike Industries J Compensator (Japan Type 89) is a very high quality product, as Strike Industries as a great reputation for. I installed this in My Colt M4, after ordering a crush washer for installation. The compensator worked very well and every range tested and performed particularly well in high winds. Also performed will in CQB training though, as with most compensators, are not very friendly to other operators in close proximity to the muzzle, and the blast is directed to the sides. Very well suited for a patrol rifle. The was also a slight reduction in recoil, which may be more beneficial to precision shooters or competitive shooters.

In researching the Japan Type 89 nomenclature, I learned the compensator is standard issue on weapons used by the Japan Self-Defense Forces, the Japan Coast Guard's Special Security Team units, and the Special Assault Team. This is a basic style of compensator and performs as advertised and is reasonably priced at around $29.
