Flattens The Competition At 1,000 Yards

The MSR 15 has never offered practical 1,000-yard performance. That's all changed thanks to the heavier bullets and extremely high ballistic coefficients of new 224 Valkyrie. Loaded with the 90-grain Gold Medal Sierra MatchKing, the cartridge offers as much as 127.88 inches less drop and 68.76 inches less wind drift at 1,000 yards when compared to existing MSR 15 cartridges.

More Punch. Less Kick.

New 224 Valkyrie provides comparable ballistics as larger counterparts like 6.5 Creedmoor but with as little as half the felt recoil.

We only use quality parts from reputable manufacturers in the industry.

This is Non Reciprocating Side Charging Upper - keeps the charging handle forward during operation. No need to take your finger off the trigger or lose sight picture to charge the weapon. Can mount your scope as far back are you desire without difficulty in charging weapon. 

This is a complete upper kit - includes everything needed to turn your stripped lower receiver into a full pistol/rifle.

Tactical Kinetics makes high quality barrels. Made out of milspec 4150 CMV and melonited for enhanced corrosion resistance and lubricity. 

The Ghost rail is very high quality and comparable to many other higher end rails that cost 2x or 3x as much. Handguard is lightweight, made from high quality 6061 aluminum and mounting system is rock solid.

Gas Block diameter is 0.750 and is made out of steel (not aluminum). Comes with the P2A Left Handed 224 Valkyrie Full Auto Nitride BCG. Made for us specially by one of the largest BCG manufacturers in the industry.

*Optional* - Upgrade to a JE Machine Tehc SOPMOD stock. 

*Optional*Upgrade to an Adjustable Gas Block. Great option if you are using a suppressor or just want to fine tune your system.

*Optional* - Upgrade to a Black or Stainless Competition Muzzle Brake. This is an enhanced version of the popular style muzzle brakes. The baffles and ports are milled larger to drive pressure up and to keep the muzzle down more effectively.
