We had two things in mind when it came to redesigning the Standard + Model; weight reduction and functionality.  Our functionality improvement came from the upper receiver and since we were on a mission to make this rifle semi ambidextrous, we decided to upgrade to a ambi charging handle.  The next upgrade came in the form of weight reduction on the font end.  We offer the Standard+ models with three rail types including the SPR/15 Handguard, the SPR/13.5 Handguard and the MK/11.875 Handguard.  The last upgrade was to improve the overall gas flow by making improvements to our gas management system from front to back.

This TYPE-A 16″ Standard+ is built on a ridged Carbine rifle platform with improved lower components to make it an incredibly versatile rifle. The Standard+ Carbine is equipped with a 16″ QPQ vanadium alloy steel barrel (for weight reduction), an improved MLOK Handguard with a SILENCERCO ASR muzzle to give it that aggressive stance. The TYPE-A SPR-16 Carbine Rifles is driven by our TYPE-A QPQ coated bolt carrier group w/R.E.M. Polish.  It’s also equipped with a DGI (direct gas impingement) system to give it consistent reliability time after time.

NOTE:  All of our rifles are Hardcoat Anodized and then Cerakoted to give you a longer lasting more durable finish.  We wanted your rifle to wear to the anodized finish vs. the raw aluminum surface.  Just another added benefit making your rifle….TYPE-A.
