UZI Steel Ratcheting Barrel Nut for Full-Size & Mini UZI

Keep your barrel securely locked in place and preserve fast, tool-free barrel changes with this heavy-duty Steel UZI Barrel Nut. Precision-machined from solid steel with a corrosion-resistant dark parkerized finish, this essential replacement component threads directly onto the front receiver trunnion to retain the barrel under sustained firing.

Engineered to original military and commercial specifications, it features a diamond-knurled outer grip surface for effortless hand-tightening and a rear serrated ratcheting ring that engages the receiver's spring-loaded barrel catch to prevent loosening during operation.

Key Features:

• Heavy-Duty Machined Steel: Solid steel construction with a durable dark parkerized finish built to withstand high heat and repeated barrel swaps.

• Positive Ratcheting Lock: Precision-cut rear serrations interface directly with the UZI receiver catch to lock the barrel firmly in place without tools.

• Diamond-Knurled Exterior: Textured outer band provides a reliable, non-slip grip for quick installation and removal by hand.

• Clean Internal Threading: Precision-cut internal trunnion threads (M26x1.5) ensure smooth engagement and consistent barrel seating.

• Wide UZI Compatibility: Fits standard Full-Size UZI and Mini UZI platforms, including IMI / Action Arms Model A, Model B, Semi-Auto Carbines, and SMG variants (does not fit the Micro UZI or UZI Pistol).

Includes: Barrel nut only.
