On Target

We just started stocking a brand new compensator from Primary Weapons Systems (PWS).  It is called the FSC-Custom.  What makes it unique is that it uses thread adapters to fit several different thread patterns.  Thread patterns available are 9/16x24 RH, 1/2x36 RH and 14x1mm RH.  The FSC-C is patterned after the .30 caliber FSC30, but it is slightly narrower at .900" diameter.  It is designed to work for calibers up to .30 cal. but it also works very well with 6.5mm and 6.8mm calibers.  The 9/16x24 threads are most common on inch pattern FN FAL rifles, 6.5 Grendal ARs, and some M1As with direct connect threads instead of the standard M14 arrangement.  The 1/2x36 threads are common on AR type rifles chambered for 7.62x39mm.  Finally, the 14x1mm threads are common on many European tactical rifles like those from Sako and Tikka.  One thread adapter is included with the FSC-Custom for the pattern of your choice.  Another great thing about this unique design is that the back of the thread adapter is designed to act as a crush washer, so there is no need for additional washers to properly mount and index the compensator on your barrel.  All in all, it is a great concept and it opens up the popular FSC muzzle brake design to a very wide variety of rifles.
