Conversion kit for AR15 cal.9x21 version - ERREDI TRADING

DETAILS
Converting your AR15 to the 9x21 caliber means being able to use your rifle at any shooting range, even just for pistols, being able to reload in a simpler and more cost-effective way, still being able to maintain all the flexibility of the AR15 platform and the freedom to choose accessories. Also, unlike conversions to .22lr, conversion to 9x21mm does not affect the "real" shot feel of a rifle.

This kit, designed to fit any mil-spec AR15, can be an excellent base, associated with a lower receiver of your choice, for a completely customized version of your weapon.

Upper Castle / Upper Receiver: Heart of the kit, completely "Made in Italy" made in Ergal 7075 with the "punch" forging technique which guarantees strength and elasticity of the material. The hard anodizing finish gives high resistance to the upper castle coating. Equipped with an ejection port with a spring-loaded dust flap and a case deflector. A Picatinny rail is made on the upper surface to house sights or optics.

Barrel: 13". Made of burnished 34CrNiMo6 steel. Semi-polygonal 6-start rifling with 250 mm pitch (typical of 9mm barrels). It has a 1/2"-28 UNF pitch threaded muzzle

Shutter: Made by Erreditrading with CMMG components. Equipped with mass closing operation. Equipped with internal extractor.

Handguard: Made by UTG Leapers. Handguard made of aluminum with 4 picatinny rails positioned at 12, 3, 6 and 9 o'clock.

Compensator: 3-stage. Equipped with 3 side vents and 3 upper holes with different diameters to limit the twisting moment given by the bullet.

Magazine and adapter: Polymeric adapter with a very well shaped lower part to make magazine changing fluid and simplified. The adapter is equipped with a spring-loaded ball pin which eliminates any possible backlash.
