Why do we have to choose between L-stocks and T-stocks when the vertical piece could easily be made to mount in both positions?

Two horizontal threaded holes in the butt-end of the horizontal arm would allow the vertical piece to attach in several positions, would they not?

In a previous response you said that ICD Desert Foxes could have become great in another generation or two. What would have made a third generation better? Can it be done to an existing Fox or would it need to be designed in from the start?

-Ooh, good question, but one that's going to be tough for me to answer. It's been a good long time since I last had a DF through here, and even then, I wasn't really analyzing it with an eye towards future improvements.

Of course, there's simple stuff like switching it to 'Cocker thread, a vertical ASA, a 45 frame and a proper 2-finger trigger, and giving it vertical feed. Apart from that, I seem to recall one of the main complaints was inefficiency- somebody could play with chamber sizes and bolt weights to see if they can't bring that up a bit. It'll never equal a modern spooler, but can probably be better. And wasn't there an ROF issue? Like the reg couldn't keep up? ICD has always had notoriously bad regs, so some better technology here would also likely pay off.

I'd have to get one in and play with it before I could speculate further. I'm definitely not an expert on this one.

Is it worth bringing to market now?

-No.But don't get me wrong, that has less to do with the 'Fox itself and more to the overall market. And the fact is, there's kind of no market for it anymore. Players today- new ones- want one of two things: Dirt cheap or high-end. They either want it as cheap as possible to get into the sport, or they want the best money can buy, because of course the more you spend on your gun, the better a player you are.

The 'Fox design simply can't compete, even upgraded, with modern spoolers or rammers. That means it'd have to be an entry level gun, and it's too expensive a design for an entry level. We'd be back to the same thing ICD found with the PRP- it'd be considerably more expensive than competitors, but without really offering much extra by way of performance. And there's very little "mid level" market markers out there right now- there's a few, sure, but WAY less than there used to be.

If we ever get back to the heady days of the pre-recession nearly-double-digit growth, with some updating it could be a viable design to bring back, in a limited way. But for the forseeable future? Nope.

Why are BOA barrels so highly regarded? Was there a secret that only BOA knew? Were they that much "better" than other barrels offered at the time? Are they matched by modern barrels?

-To answer that question, we need to go back a few thousand years.

When discussing swords, the katana is generally regarded as one of the finest styles, and the early master-craftsman-made blades the finest among those. To the point they're considered, by the... well, the unwashed masses, to be the finest ever made, and not surpassed even today.

And those masses aren't just referring to the quality and care of it's creation; no, some unknown-unto-this-day aspect makes them sharper, they stay sharper longer, can cut right through lesser swords, etc. Technology lost and supposedly unequaled even by today's metallurgy.

Which is of course, horsecrap. It's purely a form of... I don't know, call it "established rumor". The katana was the superior sword during the Edo period, so to those who don't know any better, they're still the best-ever sword even today. (Movies, TV and comic books don't exactly try to correct this misconception, either. )

What it is, is that for it's time, yes, it was a top-quality weapon. First off, they used actual steel- or at least a form thereof, where much of the rest of the world was still using wrought iron (not much different than today's mild steel.) second, the lamination of the steel with iron made a more flexible blade- an iron sword would bend and stay bent, a steel one would bend and spring back. The softer iron blades were never really "sharp", they were generally more of a bludgeoning or stabbing implement. The far sharper katana could effectively cut and slash.

And so on. And that reputation has been repeated and repeated, so that someone hearing "the best sword ever made" today, makes them think, well, in that case it must me sharper than a ceramic chef's knife, more flexible then a epee`, can chop through a granite boulder, etc. etc.

Which is of course not the case. It was one of the finest weapons of it's day, and still considered very good even today, but modern metallurgy and computer-controlled heat-treating and the like, can produce a superior blade, and in days, rather than in years.

The BOA enjoys the same sort of situation. In its day, it was a very good barrel, in large part simply because it was one of the very, very few aftermarket barrels even available at the time. Generally speaking, they were typically slightly tighter bore than a typical factory barrel of the day (though not by much) were finished a little smoother, and were hard-chromed to boot.

So they were very good barrels, and out of the maybe half-dozen or so aftermarket barrels even available back then, definitely among the best.

At the time.

Today, they're only okay. They were made back in the big-paint era, so you'll rarely see one that mics under about .688, with .689 to .692" being more common. They're just a typical smoothbore, with their one remaining feature being a generally minimal amount of porting.

Basically they're cruising on a 20-year-old reputation that's long since been superseded these days.

How would this hypothetical Fox 3 compare to a Mag? Is it worth bringing to market now?

-Of course! I'm long since out of parts, so I'll have to make it all from scratch. How much of a hurry are you in? At this point, I'd really like to get my benches cleared off by the end of the year, so if you're not in a huge hurry, I'd like to suggest either sending the gun or body in (for a proper fitting) or making the 'official' order after the beginning of the year.

Doc.

Not in a huge hurry, just itching to have it complete. I will get back to you in the new year

Where on the body do I drill a SL68 II for the gas line when building a VSC version?

-According to this ancient pic I scanned from a paper photo of my SC-SL back in 1996 (and unfortunately scaled for the 640x480 monitors of the day) ...



I'd say about an inch forward of the rear plug. Pull the rear plug and measure the depth of the valve chamber with a thin rod or stick. Use that to mark the outside of the gun, then lay the endcap on the side, and mark how far it screws into the body. Drill and tap your hole in between those two marks.

(I do still have the original paper photo of that somewhere- I've meant for years to re-scan it at a higher res. But then, I still have the gun itself somewhere, and I've been meaning, also for years, to dig it out, re-polish it, and see if I can't finally fit it with a tighter-bore barrel.)

[Magmoormaster]

I was literally right about to pm you and ask if you ever got a new bolt for this.

[Junglepeanut]

Can you make me a bolt for my Fastback? Some heathen replaced the stock bolt with a B2K bolt long before it came into my possession. Need to get the proper one in there to get it dialed in

What about tapping the existing air passages to use LP hose barbs and then fitting in an eBlade noid? The noid can take the original space occupied by the noid and drop down somewhat into the space crossing over to the battery tube. LP barbs would just need to stop before threading into the ram. Can tap them from underneath or go crazy and mill top of LED to accept a LCD noid cover and have access from the top.

-I know. I put it there for you to find.

... whatever it was.

Doc.

Matrix VASA screw to complete the build in-progress. So, thanks for crawling out of your igloo, braving the raging moose, and flying down from the frozen muskeg just to deliver that.

If you have any Matrix parts or specs, lemme know.

Cheers!

-Can but shouldn't. That's one of those things that, in my opinion and likely that of the DOT as well, if the tank threads are at all compromised, the tank should be condemned.

Yeah, I don't always like it myself, but this is one case where I'm firmly on the side of better safe than sorry.

Thanks! Having a 4500psi bomb next to my face definitely warrants safe 😄
