Meter Testing, the Witt Machine, Integrally Suppressed Ruger Precision Rifle

Before I get started, I want to thank RayDog from ThunderBeast Arms for coming out to the range with their B&K2209 Sound Meter. Ray and TBAC were gracious enough to support this project, their expertise in this area was an important component.

If you have not already checked out video stop by here.

Sound Testing the Ruger Precision Rifle

This project would not be complete with out sound meter testing. When I spoke to Alan from Machine Gun Tours about it, I wanted to bring in some one with a real sound meter. I know Alan just got back from the Competition Dynamics, Magpul Governors Match in WY. So a quick call to ThunderBeast Arms and Ray agreed to lend us a hand.

I initially contacted Larson Davis to purchase a LxT sound meter from them. Larson Davis was easily two weeks out, so I figured we would just use the TBAC B&K2209. Little did I know Ken from Witt Machine had a Larson Davis LXT. Hearing this was great news; we’d have two meters for comparison.

Ray monitoring the activity

Ray being a pro in this field schooled everyone on MilSpec testing, and the plan was to shoot both supersonic and subsonic ammo through each Ruger Precision Rifle.

On hand we the 308, 6.5CM, 6CM, and the 556 all ready to test. We only had Atomic Ammo Subsoncs for the 308, 556; everything else would be shot with full power loads.

I won’t drone on about the results, so here is everything we did with the Ruger Precision Rifles.

An Interview with Ken and Alan

This video is a behind the scenes look featuring Ken of Witt Machine and Alan of Machine Gun Tours.

The next video will demonstrate how you can upgrade an existing Ruger Precision with a Witt Machine Integrally Suppressed Kit.

The Kit contains a Proof Research Steel Barrel, a Witt Machine Suppressor, and the handguard. Installation is very much the same as changing the barrel. It requires about an hour worth of work and some AR 15 tools. It’s a super simple process.

Machine Gun Tours currently has these in stock. Both the complete rifles and the upgrade kit. The complete rifle sells for $2899, and the upgrade kit is $1699.
