The patented FSC compensator was designed to be an effective compensator for shooters in all situations. Offering recoil reduction as a primary function, and flash suppression as a secondary function, the FSC is one of the most popular PWS compensators on the market. The unique port designs effectively keep flash out of optics and line of sight, while also reducing the distracting overpressure that is felt with many compensators.

I think the fit and finish of this product are excellent. I like the idea of being able to remove the castle nut without having to worry about restaking. The QD mount is nice, though I probably won’t use it personally. The only reason I knocked one star off is because there definitely is an audible and tactile clicking (ratcheting) as you start tightening down the castle nut, but towards the end of the tightening process that really isn’t there. I don’t consider this a big issue, but it’s worth noting.
The shipping costs and speed were excellent.

Works as designed. Haven’t moved and I don’t expect it to. The QD slot for the baseplate makes attaching a sling super easy. Looking for something to make your build a little easier, here you go!

Simple and useful upgrade for AR builders. By using this, you don’t have to stake your castle nut. But even more importantly, if you need to remove the castle nut, you won’t have to break the staking to do so.

This is one of the best values in the world of AR upgrades. Not much to a castle nut and end plate right? Well if you’re always tinkering with things or are a home builder, this ratcheting system is much better/easier to install and remove from a rifle than staking the castle nut. The QD endolate is an awesome bonus as well. BTO seems to have the best prices on these.
