What is the preferred measurement setup to quantify the impulse profile (force as a function of time) to the hand or shoulder? There has to be an objective way to stop the marketing insanity of magic springs, buffers, and snake oil to "reduce recoil". Objective measurements are possible.

If I am having a 13.9" upper with a welded Muzzle device built for both suppressed & un-suppressed shooting. What buffer weight should I use with a Mid-length gas tube?

I have always wanted a Krebs or another high end AK in my collection but its out of my price range. Is it possible to make the same improvement at home or get close to his quality? If so what are the improvements? What Ak platform makes the best rifle to build from? Lastly would I be better served saving for the premium rifle or could I save a enough time and money to make it worth while?

When did the idea of a complete “free-float” handguard rail first became conceptualize, and did ARMS Inc. had some influence when the idea was first being developed? – Especially when KAC first released their RIS/RAS quad rails and which are still being issued to the military today, but they’re not free-floated. Especially since the industry has a plethora of better rails on the market.

Evening Chris and Heather, 2 questions tonight 1. Any experience with Steyr pistols? I handled a Steyr A2 MF at a local store and practically had to break my own hand to not impulse buy it. 2. Why isn't either the Beretta PX4 Store/APX more popular? I just don't get why Beretta doesn't push them the way they do the 92 series, is it because the 92 series is the military classic?

What are some reasons why a gun company would be friendly towards citizens when it comes to servicing and repairing the firearms on their own, such as CZ or Walther, and why would some companies be hostile towards citizens servicing their own firearms, such as HK, S&W, or Springfield Armory? In the prehistoric days the gun parts were custom fit due to poor manufacturing techniques and poor designs. That is no longer a valid excuse for firearms with interchangeable parts.

What are some design features of handguns to make the handguns more (or less) tolerant to sand?

Is the stepped pistol chamber a real benefit that people would ever notice, or is it more of a market differentiation item to make some pistols sound more better than others? How could a customer verify the benefit of a stepped chamber?

Kevin | $10.70

What could be some improvements to update the 1980's designs of the Glock pistols to make them more competitive in today's handgun market? Glock pistols are decent, but other companies have designed their own versions of plastic frame, striker-fired pistols that also work well.

No question, I just want to help support the channel and thank you both for the content expertise, the TX attitude, and the honest, unbias opinions of the reviewed products. Keep up the great work.

Mike

I love your channel, and I respect your style of teaching, and Its my understanding that you’re a veteran as well…I was in the 75th ranger regiment, 2/75 from 05-2010, so you can imagine my interest in your channel in general, but specifically your videos on colt, their rise/fall, and Lmt history during the gwot…We used the colt 14.5 during that time of course but my person “go to” rifle is the Lmt, I currently own the Lmt cqb Mars (mlock) with the e-bcg and 16” barrel. My question is this, I want to make a 11.5 spare no expense build that’s Lmt/Kac sr 15 quality but not as proprietary as the sr-15. I have the Lmt upper, and e-bcg. I’ll probably get the 10” sr-15 urx mlock rail but what would you choose for a barrel? Like you, I don’t care about weight. The smallest I’d go would be a gov profile but I’d go heavier if you say so, and ultimately whatever info you give me is exactly what I’ll go with. I’m not picky, I just want something that’s durable and true to their word on quality. Much thanks, and the ultimate love and respect to your channel. I’ll continue to donate every now and again, pleasure doing business with you.

Are Mark's Tech Notes ever going to be available again, or has the State Department once again banned any good troubleshooting information from being available due to the overly vague deemed export ruling for ITAR? Mark is one of the top people in the firearms industry, someone that was logical and scientific. When the Tech Notes went away the derp from the police instructors and the internet took over. We miss Mark and all that he has done in his career.

Has a fix been developed for the West German SIG-Sauer P-series pistols with the welded slides where the dual roll pins for the breechblock break? Can a commercial spiral wound roll pin be used in place of the dual roll pins, or is there a reason for the weak link in the design?

Cajun Catfish | $5.50

Bonjour from Cajun Catfish. Have you ever used a pre-sanction Russian Arsenal-imported SGL-21 or SGL-31 7.62x39 or 5.45x39? They're expensive now but I think you'd really like them. Have a good night!

Why would a handgun company purposefully design a horrible trigger pull weight and stroke?

Just have a couple questions to submit: The cold-hammer forged barrels that are sold by Centurion Arms, does Monty LeClair produce them in-house or are they made/supplied by another manufacturer? Typically when an AR-15/AR-10 internal components gets overworked or over gassed, the rate of fire of that weapon usually increases, along with wear and tear. But in contrast, the AK-47 is usually over gassed to reliably function its long stroke external-piston mechanism, it seems like the rate of fire usually stays consistent with 600 rounds per minute. Could you explain how it could stay consistent and not have a higher than normal rate of fire?

Dusten | $10.70

I understand your preference in chf chrome lined barrels but how do you feel about nitride treated bolt carriers

This can be a topic for Thursday. Handguns and rifles are designed for the adult male, the intended customers. There is a blind spot when it comes to properly designing and training women with firearms. The designers and instructors don't know what it is like to use a firearm that is too big, the problem that most adult females have. A lot of bad advice and ill-fitting products happen. As children we were taught how to design, make, and use rifles and handguns for our smaller bodies by the engineers that worked in the gun industry. We were also taught how to recognize and adapt to firearms that are too big. We never forgot those lessons that most firearms engineers and instructors never understood in the first place. What are some other ways to help the adult male engineers and instructors better understand how to make firearms work well for women? I believe that the engineers and instructors can do well, but recognizing the problem is super difficult. They do not know what they do not know.

Thanks Chris, you saved me from a horrible decision of buying a colt le6920 with no c stamp that will costed me 2,750. Also, thanks for the great content and looking forward for the next crime series.

What's the difference between the NRA conference and Shot Show? If you could only go to one, which would it be and why?

I agree with you on scientific principles, as a guy in IT who studied it in college and works in the field is never ceases to amaze me how people draw conclusions from next to nothing in evidence.

What would be the procedure to set the gas regulator on the Inch FALs that do not have the last round bolt open feature? On the Metric FALs with with the last round bolt open the procedure is to start at the lowest setting, adding more gas until the bolt locks open with the last shot. Then, add 2 clicks. Without the last round bolt open feature on the Inch FALs, I don't know how to know that the bolt is moving all the way back.
