(5 out of 5) HM DEFENSE STEALTHMS55.56
by from Middletown, Ohio on

I had an opportunity to test and evaluate this weapon system at a HM Defense range demonstration a few months back. The rifle was an absolute pleasure to shoot. HM Defense has created a rifle that can be easily manipulated by the shooter and offers a robust design. The trigger is match quality out of the box. I was impressed with the design of the adjustable gas system and the overall lack of blow back I felt from the integrally suppressed barrel when shooting the 5.56 and the 300 blackout. I will be adding both calibers to my collection soon.

(5 out of 5) Innovative design
by from Mason, OH on

Incredible, innovative design approach by HM. By having the suppressor integrated into the barrel creates a design with unparalleled performance and reliability. I used one as the base to create a unique mid range urban DMR rifle. Even though it’s a mid range build, I’m still achieving incredible performance at longer ranges with the right ammunition. Absolutely zero flash from the muzzle which is crucial in a city fight situation.

by from Harrison, Ohio on

I have used the Stealth for three years in law enforcement and over the last year as a tactical member of a local Swat Team. The performance I have seen from the Stealth is a 10/10. I have had no malfunctions; it is a joy to shoot and the technology in the weapon gas system and BCG puts this rifle in the top tier status. I have used Daniel Defense, Colt, and Knights Armament and I would choose the Stealth over any option those brands offer to serve me on duty.
