The Q LLC PorQ Chop 8.6 Blackout Suppressor (brand part no. SIL-PC-QUICKIE-86-RE) is a National Firearms Act Title II suppressor purpose-built for 8.6 Blackout and other .338-class platforms. Q LLC machines the PorQ Chop from all-steel construction finished in black nitride/melonite, giving it the durability to handle the heavy bullet mass and high pressure of 8.6 Blackout subsonic loads better than a traditional titanium can. It mounts via Q’s Quickie XL taper mount system for fast, repeatable attachment and detachment, and the suppressor is full-auto rated for sustained, high-volume fire. As a regulated suppressor, this item transfers through the same ATF Form 4 process as any other NFA Title II firearm, requiring an NFA-licensed dealer and a completed background check before delivery. Among our silencers, the PorQ Chop suits 8.6 Blackout shooters who want a hard-use steel can built to withstand high-volume shooting.

Frequently Asked Questions

Is this suppressor an NFA item? Yes. All suppressors are regulated under NFA Title II. This item transfers through an NFA-licensed (SOT) dealer via ATF Form 4, with a background check and approval before you can take delivery.

What does the transfer cost and how long does it take? As of January 1, 2026, the federal NFA transfer tax was reduced to $0 under the OBBBA. You will still need to work with an SOT dealer and wait for ATF Form 4 approval, which can take weeks depending on current processing times.

Can I run this suppressor on smaller calibers like .300 Blackout? It can physically mount to smaller-bore calibers, but it’s purpose-built and optimized for 8.6 Blackout and other .338-class platforms.
