Modernize the Uzi with the ability to mount modern accessories. Unique solution to bring UZIs up to speed and take advantage of modular accessories. Machined from solid billet of aircraft-grade aluminum and hard anodized. Mounts easily to full-size IMI UZIs. Requires slight fitting for Group Industries (i.e.. Vector Arms) receivers as they are slightly bigger in the front handguard area. Also available for the Mini-Uzi - see UTR-M
