Another example of making the most out of what is available. The Marines had a requirement for new sniper rifles to replace the long-worn out modified Garands and M-14s that they have in service. Upgrading and accurizing M-14s for sniper use would have been too expensive and required a level of expertise not readily available in the Philippines. Philippine armorers know the M-16 inside and out, though, and from it the Corps created an effective sniper weapon.
The MSSR used an unissued M-16 lower receiver, a fine tuned match trigger, and a DPMS upper receiver with a match-grade, heavy, free-floating barrel with a tubular aluminum handguard sporting a Harris bipod. To reduce cost an armored Tasco 3-9x40mm scope is used. This scope is rugged, relatively cheap compared to other models and performs well. The MSSRs need to shoot one MOA (minute of angle) or better with M855 rounds before they are issued (a minute of angle is a measurement of rifle accuracy; a 1 MOA rifle produces a one inch group at 100 yards, a two inch group at 200 yards.... etc.).
The 5.56 mm round is not a popular round for sniping but considering the limited ranges found in the Philippine countryside it is adequate, and Marine Scout Snipers can place accurate shots with the MSSR out to 600 meters.
The Marines still have a standing requirement for a proper sniper rifle similar to the US Marine Corps' M40 bolt action rifle. Once the PMC acquires the funds to purchase the rifles the the plan is for the MSSRs to be relegated to Designated Marksman weapons.
The downside of the Marine Corps' "sariling sikap" sniper rifle program was that it may have caused inter-service rivalry to rear its head. When the US delivered its military aid package in December, 2001, all weapons, including several brand new sniper rifles, were appropriated by the Army, neglecting the fact that the Philippine Marine Corps established and operates the only sniper school in the country
