308 AR Tools:
AR-10 DPMS LR-308 SR-25 AR 308 Specific Tools
Much like their smaller AR15 siblings these large bore AR rifles require very specific tools. Additionally theres more information at my other sites on basic gunsmithing tools and AR15 tools.
The Brownells 308AR Barrel Extension Torque Tool has a very misleading name. In fact my first impression after reading the title lead me to believe the 308AR 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.
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 "Claw" is the perfect armorer tool for holding all DPMS .308 upper receivers. Made of a solid one piece high strength polymer, the Claw is extremely durable. Simply clamp the Claw into a bench vise, slide the upper onto the Claw, secure with the two holding pins and begin installing your barrel and components.
The DPMS "308 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.
This wrench will work with many AR-10,LR-308 and SR-25 free float handguards.
Heavy-duty wrench provides plenty of leverage for installing and removing barrel nuts when used with a 3/8" or ˝" drive breaker bar, socket wrench, or torque wrench. Cut from 3/8" thick steel, with plenty of metal so it won’t flex under pressure while transferring the torque evenly to the nut. Models available for AR-15/M16 and ArmaLite® AR-10®.
