Defective JMAC Threaded Mount – Manufacturing Flaw on First Thread

I recently purchased a brand-new JMAC mount from Rainier Arms and ran into a serious issue straight out of the package. When attempting to thread my Resilient RS9 suppressor onto the mount, I immediately noticed significant resistance. My first concern was potential cross-threading or an incorrect thread spec, but after double-checking compatibili...Read More

ty and verifying that the threads were properly aligned, the problem persisted.

Upon closer inspection with a pick, I discovered that the resistance was coming from the very first thread. There's a small but clearly visible dent or deformity in that area—deep enough that even after a careful attempt to smooth it out, the defect remains. This is not a burr or damage from improper handling; the mount was installed using proper tools, and the threads were never touched until I attempted to mount the suppressor.

Frankly, I’m extremely disappointed. For a premium product at this price point, JMAC’s quality control should be far better. This kind of defect should never make it out the door.

I’ve reached out to JMAC directly and hope they will stand behind their product and provide a timely resolution—ideally a replacement. I doubt Rainier Arms will assist, as they're just the dealer, but I expect JMAC to take responsibility. Read Less

Loose mag fit on 5. 7 builds

Now she's tight. RANIER had the best price and picked up the ball when USPS lost my package (again, bastards), Someone will own a fine custom gun soon. Wish I cou...Read More
