It is no lie that I am a fan of Primary Weapons Systems rifles. I own both their “Modern Musket” (which is the base of my 3-Gun Rifle), and the Mark 216 (which is actually my first AR-10). I stopped by their booth for a chat even though I wasn’t planning to cover anything related to ARs.

That said, I was actually a little excited about their update to their Mark 1 series rifle which is now overall lighter and stronger (which they are now forging). They also have a couple of updates to their FSC and Triad muzzle device (which now are fully closed on the lip).

Primary Weapons Systems has simplified their adjustable gas block to have three positions. Position one is all ammo and conditions while unsuppressed. Position two is low powered ammo when suppressed. Position three is normal and high powered ammo while suppressed.

The hand guard has been redone with “PicMod” which is a hybrid between picatinny and KeyMod (which means you don’t have to attach the short runs of picatinny rail for accessories. Kind of a best of both worlds thing.

Cool scale attachment they had installed on one of the demos.

They have redone their buffer tube (which was already easy to install) to include their new “ratchet-lock” design. Still no need to stake the castle nut. It has also been lightened by about an ounce.

It also has ambidextrous controls (which a number of manufacturers are now doing and I fully applaud). The grip and stock are now from Bravo Company and it comes with a Lancer magazine.
