Yankee Hill Machine (YHM) makes suppressors, handguards, muzzle devices and gas blocks at fair prices, from a family shop in western Massachusetts.
Founded 1951, Easthampton, Massachusetts, Made in USA · Suppressors · Limited lifetime warranty · Family owned · Handguards
Yankee Hill Machine started in 1951, founded by Wallace Judd and James Graham after Graham came home from Korea. It's in Easthampton, Massachusetts and is a third generation family business, now run by Christopher Graham.
Suppressors are the core of the brand, from .22 LR cans up to .338 Lapua. The Turbo T3 is the rifle can most people know, and the Victra-20 is a 20 gauge can at about $600.
YHM also makes handguards, muzzle devices, gas blocks, barrels from about $120, complete and stripped uppers and lowers, and its own carbines.
We'd buy a YHM upper or muzzle device for a budget build without worry, and shop its cans if a suppressor is next.

Got this YHM buffer tube for my build. It works, I guess. Not amazing, not terrible. Seems durable enough. I'm kinda neutral on it. If you need a basic buffer tube it'll get the job done, but there may be better options out there.
so i picked up this yhm gas block for my latest AR project. installed it no problem, but after a few range sessions the finish started to wear off. not a big deal, but kind of disappointing for the price. overall it functions fine, just wish the quality was a bit higher.
Just got this YHM barrel. Seems like good quality, installed easy. Only 4 stars bc I haven't put a ton of rounds through it yet, but so far no issues. Hopefully it holds up long term. If you're looking for a reliable barrel, this one is worth a look.
Well, I've had this YHM muzzle brake for over a year now and it's been great. Hardly any recoil and the finish has held up really well. Shoots straighter too. Definitely recommended if you want a quality muzzle device.
the yhm charging handle is alright. it works, but the finish started wearing off after a few months. not terrible, but not the best i've used. it'll get the job done, but i think there are better options out there for only a bit more money.
my buddy recommended the YHM handguard and he was right, this thing is awesome. super lightweight but still feels solid. easy to install and the mlok slots are super convenient. been running it hard for months with zero issues. if you want a quality handguard, this is it.
Bought a YHM handguard and gas block for my AR. Everything fit and installed easy. Took it to the range and it held up great. No problems at all, everything is solid.
Honestly, this YHM bolt carrier group is legit. I've put hundreds of rounds through it with zero malfunctions. Reliable as hell and the quality is top notch. If you need a solid BCG for your AR, definitely check out YHM.
