    Looking for Former Accurate Ordnance Employees (Re: One of their builds)

    Yup- if it says MARS it's a Defiance! Any R700 wrench will do fine for that matter.

    Gunsmithing 1/2x24 Barrel Threading Ruin Accuracy?

    Re: 1/2x24 Barrel Threading Ruin Accuracy? I've never had a barrel lose accuracy after I've threaded it. Personally, I'm not a fan of how small barrel tenons are for a given caliber, but the dimensions are proven and do work fine. There are a lot of things that can be accidentally done to a...

    Gunsmithing buy micrometers.....frictin,ratchet, or plain

    Re: buy micrometers.....frictin,ratchet, or plain I agree on the carbide- definitely a good investment. With regards to the torque-limiting mechanism, I'd rather have one, but either is fine. If the mics are calibrated using the ratchet/friction thimble, they read the same no matter who...

    Gunsmithing Problem with AI mag feeding in McRee chassis

    Re: Problem with AI mag feeding in McRee chassis If you modify the magazine to work, your rifle will only work with modified magazines. There is a proper fix for it. Actually, it isn't a fix, as that implies a fault in the chassis. The mag catch is mounted to the trigger guard. The...

    Gunsmithing posibably the dumbest machining question to date.

    Re: posibably the dumbest machining question to date. Yes- 1/2" is the nominal OD if the threads. When you turn down the muzzle to make the thread tenon, you will cut this diameter to about .492"-.498" instead of .500" for a 2A spec thread. Once you begin threading your 28-pitch thread...

    Gunsmithing my opinion on fluted bolts for field rifles...

    Re: my opinion on fluted bolts for field rifles... Fluting minimizes bolt contact with the action. Capillary action that may wick moisture between the receiver and the bolt is restricted to a smaller surface area with a fluted bolt. This smaller area allows the shooter to break the bolt...

    Gunsmithing Fat Bastard muzzle break

    Re: Fat Bastard muzzle break Hi Derek- Ideally, .600 is a good thread length. Because the shoulder needs to be shaved to index the brake, thread the muzzle 5/8" x 24tpi x .575" long. After you index it, you'll be pretty close to .600". Be certain that you dial in the barrel coaxially with...
