A.R.M.S. #51 S.I.R. System A2 Carbine Length
The system for S.I.R. (TM) is formulated to fit flat top receivers for mil-spec, from Armalite, Colt and Bushmaster, in lengths of 5.56 carbine.
There might exist other flat top receivers that have been created, which may fit appropriately; however, we do not promise or provide a warranty for S.I.R. (TM) on any receivers (flat top) apart from the ones previously listed.
This sleeving system for modular receiver is a global mounting system for Handguard, which enables the barrel to float completely free while offering a strong ultra-light platform; here, literally any accessory for a particular mission can be mounted, such as lasers, thermal imager, night vision, M203, optical sight, etc.
Simultaneously, safety is offered to the receiver and it is able to make it unnecessary to substitute a destroyed receiver.
The distinction between inferior quality and premium AR 15 handguard is undeniable. At MSP, we only offer AR 15 Accessories from the most trusted brands like A.R.M.S.. Buy with confidence that we stand behind the product we sell.

New life for my old A2

I installed this unit on an older A-2 upper from Bushmaster that was replaced with a flat top... I figured I'd have no use for it and stuck it away in the back of the safe... Then I saw the #51 S.I.R., and it changed my mind!I decided to build another AR around it, and I'm extremely happy with the results! It fits great and makes a rock-solid mount for my accessories... Being specifically made for the carry-handled A-2, it's really the only game in town for a high quality upgrade!

I have a Dpms Ar with attached carry handle and I'm looking for a very steady red dot mount the info says its made for flat tops but the pic shows it on a fixed carry handle. Any help appreciated.
