Proper way to pin a flash hider to a barrel?
11/23/2011 2:15:17 PM
I'm curious here, I have a 14.5 inch M4 barrel, this upper will be my M203 host, I need to permantly attach my flash hider to get it over 16". I'm going to install a Blackout hider so I can use my M4 2000 on it, it gives me the necessary length I need, but I'm not exactly sure how to do it to BATF standards. My plan is to drill the hider out, than a little into the barrel, I then want to tap the hider out, and use a set screw tightened into it. I then plan on using solder to fill the hole flush. Is this accepteable? This way if my hider were ever to be removed I could (easier than the pin method), or should I just drill it and install a pin, and then solder that flush?
Thanks
Thanks

Per the ATF NFA Handbook: (http://www.atf.gov/publications/download/p/atf-p-5320-8/atf-p-5320-8-chapter-2.pdf)
Permanent methods of attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100°F) silver soldering, or blind pinning with the pin head welded over.

I have the correct solder, I was just wondering if a set screw is acceptable to a blind pin, its basicly the same, just the allen could be removed far easier if ever needed.

You must weld –– not solder –– over the head of the pin, which must be below the surface, so that the end of the pin cannot be seen and is completely covered by the welding metal.
Yes, you can do that with a set screw, but you need to fill the head in and over with weld. I doubt you will ever be able to remove it short of cutting the hider off the barrel. That is the point: Federal law requires that it be permanently attached.
If it is easier to remove than a welded-over blind pin, it is not legal.

It miight be easier to just buy a new 16 inch barrel.

I've never heard of having to do a pin and weld hider to make a 16" barrel for an M16. MG's are exempt from that shit. An SBR would be exempted too.

OP made no mention of his weapon being an MG or SBR.

Um the point is to get the flash hider permently installed on the barrel for legal purpose, for future reference please read the OP's post SLOWY then you can post a more adequate reply.

The whole idea is that it isn't ever easy to remove. If it was easy to remove then it won't comply with the NFA.
The operative word is "permanent" in a permanently attached muzzle device.

UM...read the post prior to this one...slowly. Is that an adequate enough reply for you now that it's the future?

And you know nothing of permanently attaching muzzle devices to a barrel? 1100* solder? Blind pinning? Welding over half of the circumference? Ring a bell? Maybe we need a remedial forum in the NFA section to accommodate the short bus questions. Hell, you may not know about constructive intent if you have a lower for your short barrel you mentioned. Maybe you can let your dog wear your schmedium body armor when fedz come knocking.

There are very detailed instructions on the pin and weld in the 'build it yourself' section.
I bought a barrel once with a soldered FH. It spun right off with a wrench. If you don't solder every day, just give up that thought before you even start.

He is asking if his method of attachment would make his weapon not fall under NFA regulations. Seems like a perfectly legitimate question to ask in these forums.

I made the same point by referring to the fact the he was going to use the resulting non-NFA weapon as an M203 host.
You are wasting your time.

Being that you are such an expert, shouldn't you know it is "constructive possesion" and not "constructive intent"?

I never claimed to be an expert. I was merely pointing out the fact that this post in this forum is better asked in a forum suited for building Title I crap. You shouldn't worry yourself with any of it anyway, as the fedz aren't regulating airsofts yet.

I'll waste even a little more time by stating that the guys in the DD forum would have more experience with that if it were the case.

I wouldn't know anything about airsofts, so I bow to your superior intelllect on those.
The only thing I own are 2 MG's, 1 SBS and 4 suppressors.
Oh, in case you can't tell, I am just joking around with you, so please don't get upset.
Have a nice day.

Well that makes it all better now...the 1's and 0's on my screen do affect my delicate sensitivities significantly when they are not organized properly. I was seriously contemplating suicide over all of this.

Oh, they will be used a lot, so you better leave me all your ammo and mags too.
