This is our custom built AR-15 Upper Assembly with Superlative Arms Gas Piston. This is the "cadillac" upper we call the SuperNova 204. 20 inch Krieger Stainless Steel Barrel chambered in 204 Ruger 1-11 Twist! Fortis Switch MLOK 15" Handguard. Mil-spec upper receiver with M4 Feedramps with Totally Free Floated Barrel. We double check head-space and test fire after assembly. This barrel will stabilize all 204 bullets up to 32 grains and most 40 grain bullets. Krieger barrels are the among the Best in the Business!

Extended Latch charging handle makes loading with a scope easier.

Absolutely no modifications required to lower. Uses the same mags as any 223/5.56. Will mate to any quality Mil-spec lower except some Colts with the Large diameter take-down pins. We do stock the adapter pins for these Colts.
 

Mil spec Receiver: 7075, T6 aluminum, flattop rail, accepts Weaver-style rings and your tactical accessories. Finished with mil-spec, hard-coat, black anodizing for protection from scratches, mars, and abrasion.

Superlative Arms Gas piston system. We have tested several other gas piston systems and have settled on the Superlative Arms for dependability and ease of cleaning and adjustment. Has positions for full piston charge, reduced piston charge for suppressors and no piston charge for single shot firing. The Fortis Switch MLOK Handguard is extremely comfortable and has a latch system to easily remove handguard for cleaning the piston system.

This is one sweet silky smooth upper assembly! It is truly impressive.

We are a FFL licensed manufacturer, but this upper can be shipped to an individual – no need to transfer through FFL. You are responsible to know the laws in your area!
