    Shipping an action????

    For the last year at the very least and probably more like 2 years individuals can no longer ship firearms or even firearms parts like grips or stocks (the only exception bring a scope) through UPS unless you're an FFL with a signed firearms shipping agreement or firearms products shipping...

    Shipping an action????

    Perfectly legal for an individual to ship a long gun through the mail. Has to be sent with adult signature required, and has to go to an FFL or to yourself (i.e. shipping it to yourself at your hunting or travel destination.) An individual cannot send handguns through USPS. Look at section...

    Wearing eyeglasses/safety glasses while shooting

    Rudy says they primarily use their own proprietary impactX material which is a urethane... Trivex is also urethane. Possibly a derivative. However, Rudy says they also use polycarbonate or trivex depending on the specific application or prescription.

    Khyber Optics Scope Mount?

    Chinese Spuhr clones have been a thing for several years now. You used to be able to get them for $40-60 on Alibaba and eBay. That's likely what this is, but with someone's logo on it. I made a few jokes in one of the threads about Spuhr clamp bars cracking that the Chinese spuhr copies...

    Barrel Torque Ludicrocity

    Mike actually made that mistake when tightening his first barrel, then chose to make it a standard Tac Ops feature rather than admitting he made a mistake. ;) I'd actually love to know more details about his chosen thread form and the the barrel and action holding tooling/fixturing to...

    If the sniper on scene doesn't have confidence in the cold bore shot, a good hostage negotiator can probably get permission for a few sighters...

    Barrel Torque Ludicrocity

    Let's double down and have a thread about what torque is needed on the tuner for it to be the most effective.

    Wearing eyeglasses/safety glasses while shooting

    If you could check your invoice at some point and find out which exact frame you ordered I'd appreciate it. I would rather not order a set based on pictures only to find out when they arrive the ear pieces are too thick to be all day comfortable under ear muffs.

    Barrel Torque Ludicrocity

    Josh beat me to most of what I was going to say, specifically that surface finish of the threads (a very important part of the K factor in T = KDF) is far more important than a bit of deviation in the pitch diameter of the threads when it comes to the torque needed to establish a desired preload...

    Barrel Torque Ludicrocity

    So when a gunsmith uses low torque values and gets good results we'll accept that data, but when another gunsmith like Mike at Tac Ops uses very high torque values and also gets exceptional results we'll ignore that particular dataset... Got it. I guess I've been interpreting and applying the...

    Wearing eyeglasses/safety glasses while shooting

    Very good info… going to have to try some. Looking through cheap safety glasses and then the scope, especially all day, is a guaranteed recipe for eyestrain and a headache for me. So far the best I’ve found and have been using for several years now is ESS, specifically the crossbow and...

    Barrel Torque Ludicrocity

    Specifically, he's talking about the tendency of the taper on the tool holder to distort and cause excess runout in the holder and tool if you overtighten the retention knob. If you tighten them too much you've permanently distorted the taper and the holder is now a paperweight. For cat 40...

    Cutting a manners varbon fiber stock.

    When we cut carbon fiber laminate in "industrial quantities" at work and it's not being done with specialized carbide burr end mills on the CNC machines we use diamond grit bandsaw blades for hand work, works great; leaves a nice smooth finish and doesn't chip or chunk the edges or leave fiber...

    I Spy New Baby Razor G3 4-24

    Indeed. In another 6 weeks I'm sure we'll have a few threads bitching about fresh 2026 price hikes on scopes and other shooting accessories. While not the same industry, for the last year some of the vendors I've been working with have been sending quotes that are valid for only 48-72 hours...

    Barrel Torque Ludicrocity

    They won't suggest torque that high as I'm sure they want to avoid their phones blowing up with people asking to return/exchange their damaged or marred up actions and barrels after trying to get things that tight with the incorrect tooling for the job, lol Just some quick math here since I...

    I Spy New Baby Razor G3 4-24

    My thoughts exactly. For around $2k +/- they were a no brainer, the bang for the buck was amazing. I have 4 G3 6-36s and still really like them. At the current full street price of $3k, I'd be looking at used stuff from other brands (I bought 3 used TT 5-25s for that) but since you can still...

    I Spy New Baby Razor G3 4-24

    I still have a receipt right here from Scott for 2 at $1900/ea. Granted that was from the "implosion sale" and I never got them from Scott, but Vortex made good on it... (Thanks again Shamus and the guys at Vortex for that!) I know about a year before that Scott had them for $1750 or 1800... and...

    Trying to pick a bipod

    Starting out when I didn't have the money to drop, for many years I used a Harris S-BRM (canting, notched legs) with a kmw pod lock. Still have it as a backup / loaner but haven't used it in years. Later I went to the Atlas V8, then the Atlas PSR (the rotating legs of the V8 annoyed me.) Still...

    Barrel Torque Ludicrocity

    Document control is always fun! Don't even get me started on document control and revision control... Was just dealing with that last week actually, the customer emailed one of the program team that was on vacation a redline that didn't make it to document control, and now I have 5 parts in...
