Parkerizing by itself is worthless and will not protect metal. The reason that Parkerizing works, is because the process causes a very tiny amount of the surface metal to become crystalized. If you looked at it under a microscope, it would look very similar to a sponge. A normal Parkerizing...

dogtown tom: The bottom line here is that there a few decent ATF Compliance Inspectors out there but most of them are other than decent. "Other" is defined as: Ignorant, unsafe, wannabe cops, supporting their own agenda, supporting somebody elses agenda, wanting to score points by whacking...

dogtown tom: The ATF newsletter that you quoted from is pretty vague and can easily be misused by anybody with authority and that's the problem. For example: You use an abbreviation that you think is perfectly understandable. You get a compliance inspection. The inspector says "No problem"...

dogtown tom: I'm not denying that the mistakes were mine but I think you might have missed the point. First, the previous inspector approved my format in writing. By not listing it as a mistake in his report, he approved it. It's called "approval by omission". In this case, he made a mistake...

We are a firearms refinishing business located in Arizona. We don't stock firearms for sale but do a few transfers for friends. Our FFL is primarily for gunsmithing and shipping/receiving. The initial inspection of the business premises was about twenty years ago and went without a hitch. In...

It'll get you close but remember: The height of the scope above the bore will have a huge effect on the close range sight-in versus the long range "on the paper". Two identical rifles/scope combos are bore sited at 25 yards. One has the scope right on top of the barrel and the other has the...

I've seen two types of rust on firearms. I'm talking about the bad kind, not just some minor surface rusting. There's the actual pitting kind and there's what I call "worm-holing". Worm-holing looks like the underside of wood that's been left laying on the ground for a long time and the insects...

Question # 1....If you have a laser etched serial number, the best bet is to stamp, engrave, etc. the same number elsewhere on the part for security resons. It's a lot harder to make a number stamped INTO the metal go way that it is to make a number "stamped" ONTO the metal go away. Question...

We refinish firearms. Our finishing process starts with abrasive blasting the individual parts down to bare metal and then building the new finish up on that fresh base. Over the years, I've come across three different application types for serial numbers: 1...Hard Stamping...This is the type...

I wouldn't worry about the noise during a home defense situation. Electronic ear muffs are a good idea but not something that I would want to mess around with at o-dark thirty for an emergency situation. Some years back, I was involved in a defensive situation and fired a .38 in close...

Greycliff Gunman: Here's what can be done. None of our Tuff-Gun finishes will work on the stock. They have a fairly high application and curing heat. Our TG-2 will work on the on things that don't get hot, move in a close tolerance fitting or are subjected to tension shock. That really...

After reading the last post, I think I need to clarify something. Our Tuff-Gun # Two finish..aka TG-2 has limitations as to what kind of parts it can be applied to. I explained those limitations but think I may have confused the issue between finishes. Our TG-2 finish has powder coat...

Our TG-2 finish is a very durable finish but it has limitations that our TG-1 finish does not have. It's not nearly as heat resistant nor is it as resistant to chemicals. We beat the low chemical resistance issues by applying the powder coat under the Gunkote 2400 Series resin. (Zinc...

rcmodel said it best. For reliabilty and ease of field stripping, it's hard to beat an SKS rifle. No little parts to get lost, no tricks, etc. They start developing problems with functioning and reliability with modifications. The more mods, the more issues they have. Plastic mags, improperly...

We apply powder coat as part of our Tuff-Gun # 2 finish. We have used it on mags and it works well but beware of a couple of things. It can cause issues with feeding if it get's inside the mag. It will tighten up the fit of the mag in the mag well so if it's snug now, it will be tight...
