Key Features

• Precision Barrel Extension: This component is the critical interface between the barrel and receiver. Why it matters: A precisely machined extension ensures consistent headspace and bolt lock-up, directly impacting accuracy at extreme ranges.
• Matched Bolt Assembly: The included bolt is headspaced to the extension. Why it matters: A matched set eliminates tolerance stacking, ensuring reliable extraction and ignition, especially with high-pressure .416 Barrett loads.
• Hardware Kit with Jam Nut: Includes ejector, extractor, and a heavy-duty jam nut. Why it matters: The jam nut secures the barrel in the receiver, preventing shift under recoil, while the extractor and ejector are tuned for the .416 Barrett case rim.
• Instruction Card: Provides step-by-step guidance for assembly by a qualified armorer. Why it matters: Proper installation is non-negotiable for safety and performance; this card ensures the builder follows Barrett’s exact specifications.

Who It’s For

This kit is for the advanced shooter or collector who values customization and has access to a qualified gunsmith familiar with the MRAD platform. It is ideal for those building a dedicated extreme long-range (ELR) rifle in .416 Barrett, where every component must be tailored for maximum consistency. The kit is not for casual plinkers; it is for the historian who appreciates Barrett’s engineering legacy and the enthusiast who understands that precision is built, not bought.

Pros & Cons

FAQ

Can I install this kit myself without gunsmithing experience?

No. This kit is intended for installation by a qualified armorer or gunsmith familiar with the MRAD platform. Improper assembly can lead to unsafe headspace, extraction failures, or damage to the rifle. Always consult a professional.

Does this kit include the barrel?

No. The kit includes the barrel extension, bolt, jam nut, ejector hardware, extractor, and instruction card. The user must source a .416 Barrett barrel blank and have it chambered and contoured to their specifications.

Will this kit work on a standard MRAD rifle?

Yes, the kit is designed for both the MRAD and ELR variants. However, ensure your rifle is configured for .416 Barrett, as the bolt face and magazine must match the cartridge.

What is the purpose of the jam nut in this kit?

The jam nut secures the barrel extension to the receiver, preventing any rotational movement under recoil. This maintains consistent barrel alignment, which is critical for extreme long-range accuracy.

Is there a warranty on this kit?

Barrett Firearms Manufacturing offers a limited lifetime warranty on their products. Per Barrett, this covers defects in materials and workmanship. Check the included documentation or contact Barrett directly for full terms.
