The SPR fills the niche for a high precision rifle with a greater effective range than an M4 carbine in a package shorter in length than a standard issue M16A2. The SPR essentially grew out of the SOPMOD Block II programme and the US Navy SEALs ‘Recon Rifle,’ and remains popular with Special Forces throughout the US military.
The Mk12 Mod 0 SPR features a number of modifications to improve its accuracy and range.The 18 inch free-floated match grade barrel has a 1:7 rifling twist to take advantage of the new Mk 262 cartridge. This new cartridge features a heavier bullet that retains more energy at long ranges. The trigger is a Knight’s Armament Company two stage trigger. The PRI Gen III free float tube is made of carbon fibre and has mounts for accessory rails spaced at 90 degrees. PRI flip up iron sights provide a backup in case of scope failure. The scope is a Leupold 3.5-10X with flip open dust covers. The full length accessory rail running over the top of the rifle is manufactured by ARMS. The Harris bipod provides a solid shooting rest. The special muzzle brake reduces recoil and is threaded for a suppressor.
The SPR holds 20 rounds of 5.56x45 NATO ammunition in a detachable box magazine.It has an effective range of around 550 metres.
