SIG Sauer 551/553 MMR/Blank Kit

UTM’s Rifle and Carbine conversions and conversion kits are designed and engineered for the upmost in safety, in-service reliability and maintainability. The conversions and kits are easy to install, typically a simple exchange of the manufacturer’s Bolt and Carrier Assembly. UTM conversions adapt the host weapon to fire UTM ammunition with the feel and function of “live” ammunition.

Description

UTM 5.56mm Man-Marker Conversions are uniquely designed to prevent the discharge of traditional 5.56mm/.223 “live” ammunition (5.56 NATO, 5.56 x 45mm, and .223 Remington). Fail-Safe is achieved by utilizing an offset firing pin design, which will only work with the rim fire primer used in the UTM Cartridge, but not with a “live” center fire cartridge. In the event a 5.56mm “live” cartridge is chambered and the trigger is pulled, the Conversions offset firing pin will strike outside the primer pocket of the 5.56mm “live” round. This makes it impossible to detonate the “live” cartridge in the UTM converted weapon.

SIG Sauer 516 MMR/Blank Kit

Contains bolt and magazine.

Description

All UTM Pistol conversion kits bear a unique chamber profile that will not allow “Live/Lethal” Ammunition to completely chamber therefore holding the weapon out of battery, making the weapon inoperative. The conversions are also slotted on the side, which allows the brass case of a live round to rupture in a controlled manner dispersing gases and unburnt powder through the ejection port if all safety protocols are not followed or a round is distorted/forced into the conversion. The UTM conversions provide safety well beyond that of any other conversion on the market, providing live round lock-out for commonly used ammunition in the Law Enforcement and Military communities with the remaining portion of uncommon rounds being dispelled with our gas dispersal safety feature greatly reducing incident potential.
