Sale .223 5.56 Pistol Upper 4.75" barrel M Lock

Pure outdoor fun, for those who want the shortest upper receivers available, Apache Armaments presents their 4.75" fire-breathing uppers. Chambered in .223/5.56, these uppers are intentionally loud, obnoxious, and light up the area. They are more accurate than you expect.


Made with a 4.75" QpQ, nitrided barrel than has been manufactured to Apache Armaments' exacting standards.  Combined with an American made M4 flat top upper manufactured from 7075T aluminum and have your choice of a 4 inch key mod or M-Lock handguard.  This item you selected is M Lock. Finished off with an A2 style muzzle brake.  

5.56 Nato chambered, 16" assembled upper receiver with 12" monolithic M-Lock style handguard. Two short sections of removeable rail sections are included. Barrels are QpQ nitride treated with carbine length gas system and a basic A2 muzzle brake. A very good basic upper receiver that Apache has been selling for years at or near the $295 price point. On sale now for $249.95*

Apache .223 Wylde assembled upper receiver with 16" Stainless Steel straight fluted barrel, A2 muzzle brake and a 12" Lightning handguard. Caliber marked for user safety.

The upper is machined from 7075T aircraft grade aluminum and finished with type 3 hard coat anodizing as per military specifications.

The Apache Armaments true match grade barrel is meticulously machined from USA sourced 416R Stainless Steel and features the .223 Wylde chambering. The Wylde chambering is a hybrid chambering developed by Bill Wylde to safely utilize 5.56 NATO ammunition while optimizing accuracy. Of course, it also safely chambers and shoots .223 Remington chambered ammunition as well. The barrel features straight line fluting in parallel to the bore axis for a slight weight reduction, increased surface area to enhance cooling and increase rigidity of the barrel.

The 12" Lightning handguard features M-lock ports on both sides and the bottom to allow the user to mount M-lock dedicated accessories or picatinny rail sections. The handguard is hard coat anodized for durability and good looks. It also features a QD mounting point on each side near the upper receiver for those wanting to mount a sling in those areas.

Like all Apache Armaments assembled upper receivers, only high quality parts are used and each unit is test fired to assure function. Of course, it is covered by the Apache Armaments limited lifetime warranty.

The upper is machined from 7075T aircraft grade aluminum and finished with type 3 hard coat anodizing as per military specifications.
