The Marine Scout Sniper Rifle or MSSR is a select fire sniper rifle developed from the Colt M16A1 rifle by the Philippine Marine Corps Scout Snipers due to the lack of a dedicated sniper rifle which is used in the Armed Forces of the Philippines.
The MSSR was developed due to the need of a sniper rifle system that could effectively use 5.56 × 45 mm NATO ammunition (most other sniper rifles use the larger 7.62×51 NATO cartridge). This was done mainly for cost-saving and availability reasons since the Armed Forces of the Philippines are actively engaged in counter-insurgency and internal security operations, especially against the Moro Islamic Liberation Front (MILF) the and Abu Sayyaf Group.
The shorter effective range of the 5.56 mm cartridge compared to the 7.62 mm was less of a factor due to the shorter ranges encountered in jungle combat, where the rifle is primarily used. Its performance during subsequent combat operations proved the effectiveness of the weapon system, and it was adopted as the primary range sniper rifle (for ranges of up to 600 m) of the Philippine Marine Scout Snipers.
The system was developed in-house under the direction of then Col. Jonathan Martir, PN (M) (GSC), N-6.
The first generation MSSR was deployed in 1996 as an M16A1 with a Tasco variable 3-9 x 40 mm rubber-coated scope on a DPMS Tri-mount atop the carry handle. This required a Delta HBAR cheek piece on the stock to align the operator's eye with the elevated scope position. The standard handguards were replaced with a free-floating aluminum forearm, and a Harris folding bipod was attached to the underside of the forearm. The standard M16A1 barrel was replaced with a free-floated 24" (68 cm) DPMS Heavy Stainless Steel Ultra Match barrel with a 1 in 8.5" right-hand twist, with an M16A1 front sight base. A J&P match trigger was installed.
The second generation MSSR was created by removing the forward portion of the carry handle and attaching the Tri-mount directly to the top of the upper receiver. The Tasco scope and scope rings were attached to the Tri-mount, which provided a lower scope-to-bore height. The Delta HBAR cheek piece was no longer required and was removed. The M16A1 front sight base was removed and replaced with a DPMS gas block. The barrel was changed to a DPMS Ultra Match barrel with a 1 in 8" RH twist, and the M16A1 stock and pistol grip were replaced with A2 versions.
The current third generation rifle retained the second generation features, but replaced the Tasco scope with a Bushnell variable 3-9 x 40mm scope with a Mil-dot reticle, mounted with three scope rings on the receiver-mounted Tri-mount. For the Philippine Marine Corps, barrel length remained the same at 24" with the 1 in 8" DPMS Ultra Match Barrel. A version with a 20" barrel was made available for the Philippine Navy Naval Special Warfare Group (NSWG).
More recently, the Government Arsenal under its present director, Major Gen. Jonathan C. Martir (Ret.), has been developing a further evolution of the rifle as part of its carbine/rifle manufacturing project. This new version is a designated marksman rifle/special purpose rifle (DMR/SPR) variant intended to "meet the requirement for a 5.56mm rifle to engage targets up to 800 meters with optics." The new rifle will feature an 18" free-floating bull barrel with a 1 in 7" twist, a standard A2 flash suppressor, a flattop upper receiver with a Picatinny rail, provisions for a bipod and semi and select fire. The new variant, designated the "Government Arsenal SPR/DMR" is set to go into service in 2015, with the production of new rifles and the upgrading of older MSSRs to the new standard. In addition, 40 units of 16-inch designated marksman rifle variants are planned to be turned over to the Philippine Army for evaluation.
Created in late 2004, the Night Fighting Weapon System (NFWS) was made for the purpose of fighting in forested areas in low-light conditions. Night vision and regular daytime scopes can be mounted on the rifle via a Picatinny rail on top of the upper receiver. The rifle is equipped with an integral sound suppressor fitted on a bull barrel (1 inch in diameter) with a 1 in 9" twist.
The first-generation MSSR used either factory 5.56mm NATO 62-grain SS109 ball ammunition or 69-grain Federal Match Gold Medal boattail hollowpoint (BTHP) cartridges. The second-generation rifle may use these rounds as well as the HSM 69-grain BTHP cartridge. The third-generation MSSR uses 5.56mm 69-grain Hornady BTHP Match or 75-grain Hornady TAP BTHP Match ammunition handloaded at the Marine Scout Sniper School.
The MSSR is the main weapon of choice for the Philippine Marine Scout Snipers alongside the newer Remington 700P Intermediate Range Day-Night Scout Sniper Rifle and the Barrett M95 Heavy Sniper/Anti-Matériel Rifle. Sniper teams usually work in pairs with the operator accompanied by a spotter, usually equipped with an M16A2 rifle with an M203 grenade launcher. Continued development of the rifle ensures its use with the Philippine Marines well into the 21st century.
If funding permits, the MSSRs will be eventually replaced in Scout Sniper service by 7.62 mm bolt-action sniper rifles. The existing 5.56 MSSRs will then be issued to designated marksmen in line Marine units.
