YHM Turbo Integral Suppressed Upper : One Stamp Shop 

When it comes to suppressed shorty AR builds, the typical path involves a short-barreled-rifle (SBR) stamp, a separate suppressor stamp, and the patience of Mother Theresa to wait for the ATF to process both. Granted, current wait times as of March 2025 are in the weeks, not months, but still, the annoyance exists. Yankee Hill Machine (YHM) has cut through that bureaucratic nightmare with the Turbo Integral Suppressed Upper Receiver Group – a one-stamp solution that delivers the best of both worlds without sacrificing maneuverability, reliability, or performance.

What You’re Getting

The Turbo Upper features YHM’s Turbo suppressor, permanently pinned and welded to a 10.5″ 5.56mm barrel, giving it a total length of just over 16 inches. Yep, you heard that right, this setup only requires a single $200 tax stamp, no need to register an SBR separately. That’s right, no awkward conversations with the ATF explaining why you absolutely must have a sub 16″ barrel to defend your fridge.

YHM also includes their MR7 M-Lok handguard, a low-profile suppressor gas block, and a flat-top A3 receiver. This creates a streamlined, ready-to-go package, (minus the bolt carrier group and charging handle, because let’s be honest, we’re all swapping those out anyway for our personal faves).

Performance & Real-World Use

Right outta the gate, this upper checks all the boxes for a CQB-centric suppressed rifle. The maneuverability is exceptional, really, keeping the rifle compact enough to clear rooms, work inside vehicles, or navigate tight spaces, all while maintaining legal 16″ rifle status. No SBR headaches, no extra tax stamps, no soul-crushing ATF wait times (well, at least not two of them).

Now let’s talk about gas blowback. Anyone who has run a direct impingement (DI) suppressed rifle knows damn well that some setups will absolutely TORCH your eyeballs with unburnt powder and gas, leaving you looking like you just walked through CBRNE with no mask. YHM mitigates that with a specifically designed low-profile suppressor gas block that reduces cyclic rate and blowback, making this system remarkably comfortable to shoot, even in sustained fire. It’s still a DI gun, but it won’t leave you looking like the Nazi guy from Raiders of the Lost Ark after he popped open the ever-holy Ark.

The sound-suppression is solid, especially considering this is a 5.56mm suppressor. It meters at 134 db which isn’t Hollywood “pfft pfft” quiet, but it’s absolutely hearing-safe with the proper ammo. That being said, use hearing pro, take it from the guy who has the worlds tiniest beeper going off in both his ears at all times from years of ear abuse. The 17-4 stainless steel and Cobalt-6 blast baffle means durability isn’t a concern. This thing is full-auto- rated and built to last longer than your interest in yet another overpriced coffee shop opening up down the street.

Final Thoughts: A No Brainer for the Suppressed AR Owner

At the end of the day, I believe the YHM Turbo Integral Suppressed Upper is one of the best values in the suppressed AR market. The one-stamp tax process alone is a game changer, but you add in the maneuverability, reliable gas regulation, and rock solid build quality, it’s hard to argue against.

For those looking to build a suppressed rifle without the headache of NFA paperwork multiplication, this upper is a slam-dunk. Pair it with a solid lower, and you’ve got yourself a capable, quiet fighting rifle, without waiting for two tax stamps and knowing the ATF has taken too many of your hard earned space bucks. Suppressor ownership might not be as easy as it should be, but YHM sure makes it easier.
