I have an unusual bolt action gun that had a mechanical linkage fail with the result that: With the safety engaged, and no contact on the trigger, locking the bolt into battery would consistently release the sear and fire the chambered round. Is it possible for mechanical failures to produce...

That Wiseman fixture is beautiful. That's what I originally had in mind, although it's not as versatile as the upper-rail-mount fixture they built at AMU. (It's also out of the price range of a hobbyist since it starts at over $20k!)

Interesting. What does the sliding upper weigh?

You mean they use recirculating ball bearings as the damper for the rearward impulse? Is that a typical damper mechanism?

Jay, obviously you're an authority on these. Other than the beautiful finish of your rails could you offer a sort of "sales pitch" for outsiders like me? I.e., do your builds incorporate features that improve performance or precision over what the uninitiated might cobble together using stock...

Very cool! Does that one that grips the picatinny rail even have a damper or return spring on it, or is that not necessary given the total sliding mass? And what does it use for bushings on the rails?

That sounds clever, and useful for even a broader range of rifles. Can you share pictures? Designs? Who builds those?

My objective is to make it easy to test a variety of AR uppers for "absolute precision" with particular ammo -- i.e., to quickly produce a 10-20 round group where there is no doubt whether shooter error affected the precision. I.e., I want a precise piece of measurement equipment; I'd never...

Has anyone seen any machine rests or rail gun receivers for precision testing AR-10/15 uppers? I.e., something like a rail base with an AR lower receiver machined to it? Hyskore has a commercial offering but overall reviews seem to be that it is kludgy and poorly made. I don't have any direct...

Two questions Is there a convenient source for a sieve sized well to separate #4 shot from .22+cal bullets? Or do I have to make my own? Those who are recoating their barrels: Is there any evidence this is necessary, or is this just precautionary? Based on the patent it sounds like it...
