    Thank you. That is the info I was looking for. It sounded so easy and I could not find any one doing it. Now I know why.

    You guys can mark me as a wanna be. I wanna beable to afford that EAG carbine but it is too much for my budget. The only thing I would change would be the sling. Awesome looking set up.

    I found an old post of yours ref pretty much the same question. I tried to PM you but the system kept crashing. Did you get set up to do the perm jobs yourself?
    For those who fought for it. Freedom has a flavor the protected will never know.

    I've seen some fantastic silver soldering on custom knives so I don't think "looks" is an issue. You almost have to get a magnifying gless out to see the solder.

    We have a lot of chrome-moly HP steam pipe at work and when it was installed the welds are "stress relieved" at around 900-1000 degrees, if I remember correctly. So, screwing up the "heat treating" would probably be my 1st guess why it isn't widely practiced.

    Plus if someone did a good soldering job, it would be hard to do a visual inspection to tell if the FH was removable. I'm sure some gungho BATF guy that did not see a pin or weld would confiscate and ask questions later?? Maybe the law requires some visual positive proof the FH can't be removed??

    If you found that person, they would be so inundated with work of various types to be too busy to do a $60 weld job for flash suppressors.
    Well said.

    My biggest complaint about silver solder jobs as typically done on AR barrels is that they don't pass BATFE's "common hand tools" test.
    The way I saw it explained is that if you can remove a muzzle device with common handtools and non damage the barrel beyond use in the act of that, then the Batfe would not consider the job to have been permanent.
    I have removed many silver soldered muzzle devices with a 3/4" combination wrench.
    That's a pretty "common" hand tool in my book.

    Here is an example of one such barrel that had been re-parkerized after the silver solder job:

    I have a 14.5" middy and had an AAC flash hider pinned. I think it would have looked alot better soldered.

    If the finish is messed up because of the high heat that would be a good reason to steer clear? Have you used the heat stop and chaulk method? If it does not work well then looks like pinning is the way to go.

    I don't see the point in spending $200 for a 14.5" bbl. I would want to go shorter for an SBR especially with the perm FH as an option. I wanted at least one non SBR to make travel easier.

    How would it ruin the value of your gun? If the heat stop and chaulk work then I would think it would make the gun easier to sell.

    If you have an SBR already, why are you getting more permanent flash hiders?

    Why not get more NFA uppers?

    When you twist off a pinned muzzle device, you damage the barrel beyond use...



    You would not believe some of the things people send me.
    That's why I take pictures.

    Irrelavent.

    When you go to sell this barrel after an inexperienced person realizes their foolish ways to get an SBR, they will lose money. The money they could have bought a tax stamp with in the first place.

    It has nothing to do with collectability.

    There is a noticeable difference when getting in & out of a vehicle and negotiating tight hallways/doorways with a 14.5"+perm flash hider vs. a 16" with a muzzle device attached.
    I already know that. That is the only valid reason for this if you live in a communist state.
