^ 'M1A series on Internet Archive, December 28, 2014'.^ M14 Rifle History and Development (by Lee Emerson).Because the rails add weight at the front of the weapon, it is more muzzle-heavy than the SOCOM 16, making it more difficult for some users to engage multiple targets quickly.

The extra Picatinny rails allow for more attachments, including scopes, grips, lights, and lasers, but also means the SOCOM II weighs 10 pounds (4.5 kg), compared to the SOCOM 16's 8.8 pounds (4.0 kg). The SOCOM 16 features a short length of Picatinny rail in front of the action, above the handguard, while the SOCOM II features a continuous top Picatinny rail from just ahead of the action to the front of the handguard, and shorter lengths of rail on the sides and bottom of the handguard. The only difference between the SOCOM 16 and SOCOM II is the Picatinny rails.

Mine was converted to a super match by Gene Barnett (Barnett Barrels) when he was an Armor for the All Guard team and I was shooting for the AK NG. I am trying to pry it from his safe queen collection. My father has a all original Springfield M1A serial number 10xxx. You can e-mail me for a complimentary copy of this in.pdf format. M1A Serial Number Chronology by Lee Emerson 100617 Short answer: The collector’s choice would be a factory built standard model M1A rifle between serial numbers 0422XX and 063000. They could probably give you a manufacture date as well as a service and repair history for all work done by Springfield on the rifle. Your inquiry would probably be best answered by contacting Springfield directly. I am not the resident expert, but I am a fan of the M1A so I'll be the first to congratulate you.
