Strike Industries JCOMP Gen2 (1/2×28, .223/5.56)
The SI JCOMP Gen2 is the classic Type 89 compensator re-engineered and updated for the 21st century. Due to end-user feedback, the favorite features of the original are retained. However, the J Comp now features increased muzzle rise compensation and is available in 7.62x39mm and .308/7.62x51mm, in addition to 5.56×45/.223. Now also compatible with Oppressor and FerFrans concussion reduction devices.
The J-COMP concept originates from the Type 89 Japanese assault rifle, which is used by the Japan Self-Defense Forces, the Japan Coast Guard’s Special Security Team units, and the Special Assault Team.

Strike Industries and Good Service
I ordered this because they said they had it in stock. They were the only ones who did and I was shocked to see they sent it out within a day. I will be buying from here again!
