May 10, 2008

While I was going through some of our pictures from NDIA Small Arms Systems Symposium 2007, I came across some action photos of the HK MP7A1 PDW (Personal Defense Weapon) with a Gemtech "Brick" rectangular silencer/sound suppressor attached, including one of me firing the weapon/silencer combo, myself. Anyway, I thought I’d share it with our readers since I haven’t seen a picture of it anywhere else, and the Brick’s rectangular/angular shape is somewhat unusual.

DefenseReview mentioned the "Brick" muzzle can back in May 2007 after we tried it out at the symposium demo shoot at Blackwater USA. The "Brick" is…

short in length for maximum compactness, which provides for maximum operational utility like carrying the weapon/suppressor combo concealed under clothing (the Brick’s flat-sided aspect maximizing this capability), deploying inside vehicles, and perhaps even employing in dynamic CQB/CQC (Close Quarters Battle/Close Quarters Combat) environments. However, DefenseReview questions the advisability of using a 4.6x30mm weapon for CQB/CQC, since the round is very small and not exactly combat proven. It is, however, armor-piercing/armor-penetrating.

Anyway, the Gemtech Brick Sound Suppressor/Silencer quiets the MP7A1’s sound signature quite a bit, so the primary sound will be the crack of the 4.6mm round breaking the sound barrier. The HK MP7A1/Gemtech Brick silencer is a slick little package.

Author’s Note: Since they didn’t have an optical sight/combat optic on the weapon, I had to utilize the flip-up BUIS (Back-Up Iron Sights). The BUIS worked fine at the relatively short distances involved.
