Used Suppressors

    My LGS has a few used 5.56 cans for between $250 and $300. They have Gemtechs and another brand, I don't recall. All are direct thread and were trade ins from the SWAT teams of a midsize city (Temple, TX) so high round counts. They came mounted to 10.5 Colts but are being sold separately. The rifles are for sale as well and have seem some hard use. Some of the cans look to be in good shape while others display what appears to be degradation of the baffle holes. It looks like erosion but could be baffle strikes. Given the automatic $200 additional cost and long wait I can't see going cheap for such a purchase but was curious if any others had thoughts on the matter. I have read though that cans actually can get quieter with time because of all the carbon deposits but it seems the baffle hole erosion would offset sound dampening from carbon.

    I'd say buy a new one. Tax is the same and you'll know it's a good unit. Not much of a market for used ones I've always been told.

    I'm usually a big proponent of buying used cans because the majority of people treat their cans well and you can usually get some really good deals because the market for used cans is practically nonexistent, meaning you have very few other buyers to contend with.

    That said however, I would not buy a .223 can that had been used like that. Most manufacturers won't warranty their cans on barrels that short for good reason: baffle erosion. Enough use on a barrel that short and you will eventually need a new baffle stack/core. I would also be willing to bet a lot of the use was quick firing that would really heat up the can which is definitely not good for its longevity.

    All in all, I'd pass on these cans.

    Would it be economically feasible to have a can rebuilt by the manufacturer or would it end up being more expensive than just buying new?

    The only really financially viable option for cans like this is transfer tax-free to other LE outfits that want training cans for cheap. Once you put the tax stamp on them, as a percentage of total cost, you are in the territory of "why bother?". That's of course unless they are the latest generation of the big makers, in which case... <shrugs>... it's your call.

    Gemtech's customer service and quality are good enough that I wouldn't hesitate to purchase one of their used suppressors.

    You can, of course, buy a used can directly from a governmental agency, via form 5, without having to pay a transfer tax. I'm in the process of doing that right now for a transferable Mac 10 with suppressor.

    Gemtech offerred to "modernize" that old Mac suppressor for $150. Sounds like a bargain, to me. ;)

    Gemtech is by no means on the high end of the quality suppressor scale. I'd definitely pass.

    I would agree a shot out gemtech will be just as loud as a new in box one, your buying a really expensive muzzle break when you buy gemtech. SBR's are hard on suppressors, many companies will state on their web site if the can is rated for SBR use or not.

    I would pay another 150-200 for a mid range new one before I would buy a used one, unless you have excess funds and need another suppressor for your SBR.

    That is news to me. How can you avoid the $200 tax unless it is being transferred to a government entity or museum?

    Take a look at the Form 5. l It's for transfers to or from a governmental agency. There is no preclusion from a transfer being made to a private citizen.

    so theoretically a gov agency could be setup that only did this: (in some friendly state of course)
    "Buy suppressors direct from manufacturers and resell them to citizens of that state while avoiding the $200 tax and making a profit to run the show."

    How does one get lucky enough to convince a government agency to transfer their old SBR's and cans to him?

    How are you getting around the requirements in the NFA Title 26, Chapter 53?
    The law goes on to exempt licensed dealers, importers and manufacturers also. I don't see anything about obtaining a tax-free firearm from the government at all.

    Unless you are a government official I don't see how you can do this.

    Just because a form says you can get a title ii gun from the government without paying the tax this doesn't mean the law allows it. Has the application been approved yet?

    Non-sense. In actual testing all the makers are arguing "superiority" over 2-3 db differences which is about what it take for an untrained listener to reliably detect A is louder than B or vice-versa. If you look at detailed readings you'll often see this much variation within a string of 10 shots with the same can on the same gun.

    This is true, in fact assume its true that they are not rated for SBR usage unless stated otherwise.

    GemTech states on their website and in the owners manual that 11" is the SBR minimum barrel for their 5.56 suppressors.


    There are two main reasons: "uncorking pressure" which could be solved with a stronger, heavier design, but bullet stability issues that could cause baffle strikes is a larger problem that would require a larger bore reducing effectiveness or requiring even more length and thus mass.

    Many departments have budgets that require they spend money to maintain their budgets, or add to them.

    So, Ranb, who is the transferor, in my scenario? Governmental agencies are not charged a transfer tax, whether buying or selling (or gifting) NFA items.

    You supplied your own answer in the quote that you furnished. There is no tax, to or from a governmental agency, and there's no prohibition from a governmental agency's transferring an NFA item to a private citizen.

    They were attached to a pair of 10.5 colt AR's. Apparently the shop had to first ultrasound them while on the barrel in order to get them off. The AR's were pretty beat up.

    The cops may also have wanted to simply upgrade or convert to a different system such as quick detach.

    Yeah, I saw that. Awfully convenient given the prevalence of 10.5 Colt AR's.
