Looking for an extra five inches? Primary Weapon Systems (PWS) has an answer for your FN SCAR short rail woes.
The PWS SCAR Rail Extension (SRX) is a drop in, anodized aluminum quad rail which allows forward mount bipod, light, or other 1913 attachments. The PWS SRX also gives an additional two limited roation QD mounts, one of each side of the rail.
Installation of the SRX does not interfere with the ability to quick change the barrel, and operation of the gas block is not hampered. Installation, and disassembly of the piston system is also possible without removing the rail.
The PWS SRX will fit the entire FN SCAR series of weapons including the SCAR 16s, SCAR17s, SCAR L, and SCAR H. With a MSRP of $199.95, its a nice option to have if you use a SCAR. Click the below picture for additional specs, and an installation video.
