PWS SCAR Rail Extension

This is absolutely brilliant!

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
