    TriArc TSR-15 Service 5.56MM Rifle with 16" Pinned Barrel and a Black Anodized Finish.

    TriArc’s TSR-15-SE-556-139-BLK Custom Builder Service Rifle is an expertly balanced weapon that does not compromise on quality. TriArc built this rifle around their signature 2.0 TRACK barrel, making it one of the toughest and most reliable firearms on the market.

    The weapon’s balanced profile TRACK barrel is a hybrid form of standard and polygonal rifling which reduces bullet deformation, allowing it to move in a straighter line towards the desired target. Additionally, the tighter seal significantly reduces any forward escaping gases, causing minimal loss of gas pressures and increasing the overall accuracy of the bullet.

    The rifle’s durable 4150 Chrome Lined barrel is 13.9” with a permanently attached pinned muzzle device, lengthening it to 16”. The barrel has a 1:7 twist rate and is chambered for 5.56MM.

    The service rifle features a Mid-Length Gas Operated System and a Geissele Stainless Steel Super Gas Block with a .750” diameter and set, screwed and pinned. The Geissele Stainless Steel Super Gas Block is extremely durable and designed to be corrosion resistant. It also uses set screws and a gas block to hold it in place on the rifle.

    The rifle features Dead Air Armament 5.56MM Key Mount Muzzle Brake so end users will experience minimal concussion and can be quickly attached to Dead Air Armament suppressors.

    The weapon’s Geissele 13” Super Modular MK14-LOK Rail offers gun owners a slimmer design, creating a tried and trusted platform. The rail itself is made from 6061-T6 Aluminum, making it durable yet lightweight. End users also have the option of customizing their rifle by mounting lights, bipods, and other accessories to the rail.

    The SanTan Tactical STT-15 Billet upper and lower receiver is crafted from hard-wearing American aluminum and is able to accommodate any shooter because of its ambidextrous feature. Whether the gun owner is right or left handed, this feature allows end users to function well in any tactical situation.

    The TSR-15 SE service rifle also features a finely-tuned Geissele Super Semi-Automatic Enhanced SSA-E Two Stage Trigger that offers superior control and accuracy. This specific trigger is the ultimate choice for end users looking for a smooth take-up and crisp 2nd stage break.

    The rifle’s Radian NP3 Raptor Ambidextrous Charging Handle allows the end user to perform rapid palm blading or finger thumb charges in a more fluid motion from either their strong or support side. Because of the NP3 coating, the charging handle is easier to clean and remains protected in any harsh environment.

    Designed with a sleek modern profile, the service rifle’s Magpul SL Stock/Buttstock is an added plus for the weapon. This particular stock features a sloping cheek weld and anti-slip surface, ensuring a more comfortable fit and smooth transition on the range or in any tactical situation.

    The TSR-15 SE also features an ergonomic MOE Grip that is textured and anti-slip. The hand fit MOE Grip is simple, yet highly functional and able to endure any harsh elements.

    The TriArc TSR-15 SE service rifle is coated with Type III Hard Coat Anodized, making it abrasion resistant and extremely long-lasting. Finally, TriArc’s experienced armorers have crafted and modified this service rifle to endure any environment, making it a weapon gun owners can trust for years to come.
