AR-10 .243 Win 22" Stainless Steel Tactical Upper Assembly – M-LOK, Tanker Brake

AR-10 .243 Win 22" Stainless Steel Tactical Upper Overview

The AR-10 .243 Win 22" Stainless Steel Tactical Upper Assembly sits between our 20" and 24" uppers: a 22" 416 stainless steel barrel, hardened to 26-32 RC and button rifled with a 1:8 RH twist, gives extra velocity for long shots without the full length of a 24" barrel. A nitride Tanker brake keeps the rifle flat during recoil.

Specifications

Key features

• 22" stainless barrel: more velocity than 20", lighter than 24".
• Button-rifled 1:8 twist stabilizes heavier .243 bullets.
• Tanker brake for reduced recoil and muzzle rise.
• Free-float M-LOK rail.

Note: Bolt carrier group and charging handle are not included. Use a standard .308 Winchester AR-10 BCG and charging handle; .243 Win shares the .308 bolt face. Images may not be an exact representation of the product.

FAQ

Which .243 bullet weights work with a 1:8 twist?

A 1:8 twist stabilizes the full range of common .243 bullets, from light varmint loads up to heavy 100-105 grain hunting and match bullets.

Will this .243 upper fit my AR-15 lower?

No. .243 Winchester is a .308-family cartridge and needs a large-frame AR-10 lower. This upper fits Moriarti and DPMS-pattern (LR-308) low-profile lowers; fit can vary on other large-frame patterns.

What magazines and bolt do I need?

Standard .308 / 7.62x51 AR-10 magazines and a standard .308 AR-10 bolt carrier group work with .243 Winchester.

Do I need an FFL to buy this upper?

No. An upper assembly is not the serialized part of the firearm, so it ships directly to you where legal. Check your state and local laws before ordering.
