    Why not permanently attach a Flash Hider w/ +1,100 degree silver solder?

    Have any of you guys permanently attached a flash hider with +1,100 degree silver solder? Here are a few products from Brownells that look like they would get the job done.

    I like the idea of being able to do it myself and being able to change a FH without destroying it. I just wonder why I do not hear about more folks doing it. Cutting off a Phantom would not be too expensive but a Battle Comp or an AAC mount/FH is kinda expensive to be throwing away. The solder looks easier and like it would look better. Do people pin because it is easier to visually inspect the perm job? Is there risk of damaging the rifling?

    I too would like to know more about this. I don't know any shops that offer this service, all I have seen is pin and weld. This could be for liability reasons.

    What I have read is that you apply 1100 degree silver solder paste to both sets of threads. Aplly heat stop on the exposed (non threaded) part of the barrel and any kind of chalk on the last 1/8 inch before the end of the barrel. The chalk prevents the silver solder from adhering to the barrel and the heat stop is supposed to protect the barrel as well. Once the prep is done you attach your flash hider like you normally would and make sure it's timed the way you want it. Once it's set you heat the flash hider only to 1100 degrees which requires getting the flash hider to a deep blood red look and wait for the solder to start running out. From there it's just a matter of letting it cool naturally (ie not quenching in water). Test once cool to see if the flash hider will come off.

    With that being said sounds easy enough to and I am surprised more shops/people don't do it this way.

    Reasons:

    It looks like shit.

    It has the possibility to screw up the heat treatment of parts.

    It makes you a wannabe.

    It ruins the value of your gun.

    Buy a 16" barrel or SBR instead.

    Rush,

    Those are the same instructions I read.

    Scotty,

    Not sure about the wanna be? I have an SBR and I am three months into the wait for the approval of my second SBR tax stamp.

    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.

    There's one valid point for debate.

    If you are a collector who doesn't shoot your guns, then this might be a concern to you.

    Many of us can't own SBR's due to state restrictions. A 14.5" barrel with a perm flash hider is the shortest overall length carbine folks who are restricted from owning SBR's are legally allowed to own. 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.

    That fact that it doesn't serve YOU any practical purpose, doesn't make those shooters that it is practical for "posers".

    It's very rare to see someone good enough to weld it so that you will not require a lot of finish work to make it look "factory". 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.

    If you did it yourself without the proper knowledge, you get whatever you get. It might be permanent, but it might also be permanently ugly as hell. It could also change the strength or hardness of a pretty key piece of your barrel.

    I suggest you proceed with caution unless you are a knowledgeable welder, machinist, gunsmith, or other metalworker.

    As to the wannabe comments, they need to get knocked right the hell off.
