The Q LLC Tall Boy 7.62mm Suppressor (brand part no. SIL-TB-QUICKIE-762) is a National Firearms Act Title II suppressor rated for 7.62 NATO/.308 Winchester, .300 Blackout, and .300 Win Mag. Q LLC machines the Tall Boy from premium steel finished in black nitride/melonite, and this listing includes the rearend muzzle device needed to mount it via Q’s Quickie Fast-Attach taper mount system for fast, repeatable attachment and detachment. Q built the Tall Boy specifically to maximize sound suppression on subsonic .300 Blackout loads while still handling magnum-class 7.62 pressures. 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 Tall Boy suits shooters running multiple .30-caliber platforms who want one suppressor rated across 7.62 NATO, .308 Win, .300 BLK, and .300 Win Mag.

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.

Does the included muzzle device count as a separate NFA item? No, the rearend muzzle device is unregulated mounting hardware for the Quickie system — only the suppressor tube itself is the NFA-regulated part.
