PRO version conversion kit cal.9x21 for AR15 - ERREDI TRADING

DETAILS
A conversion kit to adapt any Mil-Spec AR15 from the original .223 Remington to the more compact and economical 9x21mm.

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 34CrNiMo6 steel with nickel-plated finish. 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.

Loading lever: Made by CAA, ambidextrous version to facilitate rearming speed.

Handguard: Made by UTG Leapers Made in USA. Handguard made of aluminum with "Free Float" design to ensure stability and reduced vibrations. Featuring an 18-slot upper Picatinny rail that aligns with the upper castle rail to form a single surface. Compatible with KeyMod system, equipped with 7 KeyMod rails to allow different attachment angles for accessories

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.

N.B.: On request it is possible to request the barrel in a sandblasted and blued version; it is also possible to request that the handguard be excluded from the kit.
