The Yankee Hill Machine 5.56mm Turbo Integral Topend is a complete, tax-stamp-efficient AR-15 upper receiver assembly built around an integrated suppressor system. If you're after a short-barreled rifle that runs suppressed without eating up your tax stamp flexibility, this is built for that mission. The Turbo T2 suppressor is pinned and welded to a 10.5" 5.56mm barrel, keeping the combined length just over 16 inches—well within SBR territory without requiring a separate suppressor registration. You get one tax stamp instead of two, and a system that's engineered to work as a complete unit from day one.

What you're buying here is more than just a barrel and can. Yankee Hill included their Rifle Length Black Diamond M-LOK handguard, which gives you plenty of real estate for mounting lights, grips, or other furniture. The upper receiver is a flat-top A3 design, the bolt carrier group is mil-spec, and the gas system is tuned with a specially designed low-profile gas block that tames blowback and cyclic rates—important when you're running suppressed and want the gun to behave predictably. All the small parts are there: charging handle, gas tube, and everything needed to assemble a functioning upper.

The Turbo T2 suppressor itself is built from 17-4 stainless and Inconel, finished in matte black Cerakote. It's rated for full-auto 5.56mm, so your semi-auto duty rifle won't stress it. At 134 dB suppression, you're looking at genuine hearing protection, not just a muzzle direction indicator. The whole assembly weighs 4.38 pounds—respectable for a 23.5-inch top end that includes suppression, handguard, and BCG. This is a setup that rewards builders who want a short, quiet, complete upper without piecing together compatibility puzzles.
