Mount built in: USSOCOM requirements dictated dual quick release throw levers designed specifically for the Picatinny (MIL-STD-1913) mounting rail:
• Certain commercial variants of the MIL-STD-1913 rail specification may not be compatible with the SU-231/PEQ (M553) mounting assembly.
• The SU-231/PEQ (M553) base consists of (2) ARMS® throw levers and is only adaptable to rails that properly accept the ARMS® design.
