This platform is built on a 10.5" M4 Profile 41v50 barrel with a 1/2X36 thread pitch.
This Direct Impingement SBR runs a Carbine Gas System for Reliability.
Our 5.56 NATO Carriers go through a R.E.M Polish process prior to Nitride coating. The R.E.M Polish process reduces friction, improves part durability, improves oil retention, and improves contact & bending fatigue.

Our pistols run an fully adjustable 45/90 degree short throw safety selector and an extended magazine release to give you that perfect feel.

Keeping Your Gun Running

"If you’re new to an AR platform, here’s the best advice I can give when it comes to cleaning and lube: Run your bolts wet.  You obviously want to keep it clean.  Should you clean after every range session?  Yes.  Is it the end of the world if you don’t?  No.   A well-built rifle like the TYPE-A's can take abuse and run dirty.  They just perform better, and last longer, the more you clean them.  In order to keep them cycling with all sort of different ammo requires good lubrication. The areas to focus on are the bolt and carrier.  As you’re reassembling, give the bolt a healthy dose of lube as well as the carrier.  Not to the point of dripping off, but just shy of.  Understand the less viscous the lube, the quicker it will burn off and dry out. Using something a little thicker will last longer in your gun.  I’ve known guys who used motor oil. These guns aren’t picky as long as you keep them wet."
