Delayed roller blowback system offers an incredibly smooth shooting experience unlike traditional blowback systems. Precision fluted chamber ensures unparalleled reliability and cycling.
The 8.86 in cold hammer forged barrel features the MP5 three-lug muzzle plus 1/2x28 threads, protected by a knurled thread protector marked "1/2–28." This setup supports common 9mm muzzle interfaces while preserving the classic tri-lug profile.
Controls are true to form and highly usable: an ambidextrous pictogram Safe/Fire selector, both paddle and button magazine releases, and the signature left-side charging handle. Sights are the correct HK set with a protected hooded front post and a 4-position rotary diopter rear for precise, repeatable adjustments.
An aftermarket Midwest Industries M-LOK aluminum handguard (U.S. Patent D840,494S) is installed, providing durable mounting slots while maintaining a slim, heat-dissipating profile. The pistol ships with a polymer rear endcap with sling loop installed (no stock or brace), and capacity is listed at 31+1 with the included 30-round steel magazine.
