308 AR Tools

AR-10, DPMS LR-308, AR .308 AR Tools

       January 12, 2019 Update: It’s interesting to look at this page knowing it’s nearly nine years old as I type this. While this page is still relevant there has been so many changes to the platform with many new manufacturers building rifles there is also no shortage of smart people designing tools for working on all AR platforms. This page will not receive any additional updates, however there is a new page devoted to AR 308, AR-10 and G2 .308 AR’s. Click the following link to visit the new AR-10 .308 AR Tools Page.

The original content remains in tact below 

Much like their smaller AR15 siblings these large bore 308 AR rifles require very specific tools. Additionally there’s more information at my other sites on basic gunsmithing tools and AR 15 tools.

308 AR Barrel Extension Torque Tool

Brownells 308 AR Barrel Extension Torque Tool

The Brownells 308 AR Barrel Extension Torque Tool has a very misleading name. In fact my first impression after reading the title lead me to believe the 308 AR Barrel Extension Torque Tool was for tightening the barrel extension to the barrel. THAT IS NOT THE CASE. This tool is for preventing damage to your upper receiver when tightening the barrel nut.

Description:

Handy tool aids in applying straight-line torque for fast, easy installation of the barrel nut without scratching the exterior of the upper receiver. Helps ensure the right amount of torque is evenly applied, while maintaining proper alignment of the barrel, upper receiver, and gas tube ports. Use with any barrel nut wrench or free-float tube wrench and a torque wrench with a ½” square drive. Simply clamp the barrel nut wrench handle firmly in a bench vise, insert the barrel into the upper receiver, and finger tighten the barrel nut. Slide the barrel through the wrench, insert the Torque Tool in the back of the receiver until the teeth lock into the locking lugs in the barrel extension, and apply torque with the torque drive through the Tool to tighten the barrel nut. Precision machined from heavy-duty steel bar stock for years of reliable service. Available for the 308 AR.

The DPMS “308 AR Lower Receiver Vise Block” is similar to an AR15 vise block. The plastic block is inserted and locked into the magwell like a magazine. The block is then firmly clamped in a vise. This is a must have item for working on lower receivers.
