This Foxtrot Mike Products barreled upper is a purpose-built suppressor host that ships without a bolt carrier group or charging handle, so you can finish the job your way.

Meet the barreled upper built for today’s suppressor-first shooters. We tuned this 16" system from the ground up to live its life suppressed—delivering a flatter impulse, less blowback, and rock-solid reliability without the hassle of an adjustable gas block.

Why it’s different

• Suppressor-tuned gas: Rifle-length gas on a 16" barrel with a carefully sized port reduces back pressure and tames recoil when shot suppressed—while maintaining consistent function across common loads.

• Heavier, harder-use barrel: A stout, heavy-profile barrel shrugs off heat, resists POI shift, and extends service life for high-volume suppressed shooting.

• Cleaner shooting experience: Purpose-built for cans, it minimizes gas to the face and keeps the gun running softer and cleaner.

Build details

• Barrel: 16" heavy profile, 1:7 twist, 1/2x28 muzzle (suppressor-ready)

• Gas system: Rifle length, suppressor-optimized (no adjustable block required)

• Upper receiver: Slick-side billet with dust cover installed

• Handguard: 15" free-float, M-LOK® compatible, anti-rotation design

• Finish: Durable, uniform matte coating for a clean, modern look

• In the box: Complete barreled upper as described

• Not included: Bolt carrier group (BCG) and charging handle — intentionally omitted so builders can choose their preferred components

Built for the designated suppressor host

If you plan to run a can 100% of the time this upper is for you. Pair it with a quality full-auto-rated BCG and a mil-spec charging handle (or your favorite upgraded handle), pin on your suppressor, and go.

Federal law has been updated to reduce the NFA tax for suppressors to $0 starting January 1, 2026; the NFA process and approvals still apply. Current ATF eForm 4 approvals are exceptionally fast by historical standards. Congress.govMain WebsiteATF
