A must have for scar owners - KNS Precision The Discarder

The Discarder is very easy to use. I was able to install it with the full-length MREX and make the adjustments on it by flipping the front sight up. It made the Scar 17 softer shooting, which will cause less damage to the internals when using a high-back pressure suppressor. Two two gas settings the default comes with are not enough. I highly recommend one of these as you'll have 14 settings! It also comes with other gas screws if you need them. You'll need two separate settings when shooting suppressed and unsuppressed. An indicator on the device tells you what you're on so there's no guessing or counting when making adjustments.
