PLEASE NOTE: These uppers fall into a different class than our typical blemished receivers. If you’ve seen one of our standard blems then you know that our standards are extremely high. These are considered a grade below. The blemishes consist of very small segments of raised metal (roughly the width of a fingernail). It may look like the plating has bubbled in a few spots but it’s actually very small pieces of aluminum that are not uniform. None of which will effect functionality as these tiny spots are on the outside of the receiver.

These come stripped without forward assist or ejection port door.

They have residual white powder from the plating process that easily wipes off with an oily rag.

In no way shape or form will these blemishes affect functionality.

Electroless Nickel Teflon has continually proven to outperform traditional Anodizing and Phosphate coatings by leaps and bounds! The increased reliability, corrosion resistance and ease of maintenance make this upgrade a no-brainer.

· Forged & Machined by Cerro Forge (Key Hole)

· Machined From Mil-Spec 7075 T6 Forging

· M4 Feed Ramps

· Proprietary Electroless Nickel Teflon Finish

· 100% increase in corrosion resistance compared to MIL-A-8625 hard coat anodizing.

· 240% increase in lubricity compared to MIL-A-8625 hard coat anodizing.

· 160% increase in lubricity over hard chrome.

RUN IT LONGER AND HARDER. Lubrication optional. If you decide to use lube you won’t notice when it dries up. The natural lubricity of Nickel Teflon has a much lower coefficient of friction than phosphate treated steel with lube applied.

LUBRICITY & WEAR RESISTANCE. Lubricity plays an essential role in optimizing wear resistance and longevity. Nickel Teflon has a .05 Coefficient Of Friction (COF), creating a surface more slick than Anodizing, Hard Chrome or even Nickel Boron.

LONGEVITY. Has a Hardness of Rockwell 54. Guaranteed not to peal or flake

EASE OF MAINTENANCE. No scrubbing required. Carbon fouling literally just wipes off with a rag.

CORROSION RESISTANCE. We apply a proprietary Electroless Nickel substrate with a higher than average phosphorus content, giving the coating a barrier that’s practically impenetrable by corrosion.

Note: Nickel Teflon will buff out and produce polished spots on contact/friction points. When using a clamshell type receiver block, the contact points may cause slight discoloring on the exterior of the receiver. This of course is strictly cosmetic. However, if you’re trying to avoid discoloration then we recommend using a (pin type) receiver vise.

(Inside Diameter for barrel extension is slightly undersized for a tighter fit to the barrel and a more accurate rifle.)
