You are allowed to go "visit" your can and shoot with it if your dealer has a range. And an additional wait time if you choose to buy from out-of-state and need it transferred to a local dealer first. To give you an idea...I bought two last year, both in the late Aug/early Sep timeframe, and haven't seen them, yet. Expecting them in the next week or two based on current trends. |

Kansas allows Suppresors, Machine Guns, SBR's and AOW's for personal ownership.
We also have the "Made in Kansas" bill which allows a resident of Kansas to build a suppressor without using a Form 1 to the ATF. As long as it is for personal use and not for sale. I would not risk that with the ATF and would buy some $200 insurance (Form 1 with $200 Check) to cover my ass. Federal Laws trump State laws so it is better to be safe than sorry. |

I am new to suppressors and this forum, so I would imagine this question has come up before. I submitted my tax stamp app in April and hopefully will get it soon. My first build will be fairly basic for .243 Win, using 34.3 mm freeze plugs as baffles. QUESTION: Is there a standard or optimum over-drill/clearance for the baffle passage? The clearance or gap between the bullet and the passage or tunnel it travels through? I have been advised that a good standard would be .026 mm gap or over-drill from the actual bullet size = a .269 passage for the .243. I have found two bits that are very close: a letter "I" bit at .2720 giving .029 clearance - or - a "H" bit at .2660 giving .023 clearance.
If this project works well, I plan a later, longer over-barrel .308 suppressor using a 8,5 metric bit at .3346, giving .0266 clearance. Am also now getting some feedback that this tolerance is way to close --- suggestions that .060 clearance/gap is more to standard???? This is of course a pretty critical part of the build, soooo --- Am I stumbling down the right path here ?? |

If you mailed off your form 1 in April, as an individual, you have a solid 4+ months more to get your stamp.
If you filed on a trust using the eForms, maybe a month more. Waiting times are starting to speed up, but still... For building from scratch, you can find a lot of information here and over at silencertalk. |

People typically use a 3/8" bit for .30 cal freeze plugs because 3/8" bits are so common |

I found this info really useful regarding engraving.
If you are holding an Application for Tax Paid Transfer and Registration of Firearm (labeled on the top right of the form), or ATF Form 4 (labeled on the bottom right of the form), then you are not a manufacturer, importer (into the U.S.), or maker of the firearm, thus there is no engraving requirement. If you are holding an Application to Make and Register a Firearm (labeled on the top right of the form), or ATF Form 1 (labeled on the bottom right of the form), then you are either a manufacturer or maker of a firearm, thus there is an engraving requirement. |

That's about as basic a bit of info as anybody getting into the NFA world should know. If they don't, they've done themselves a disservice by having done insufficient research before submitting a form. An F1 is to make (build)...so you're a maker, nothing else. Importing and manufacturing is a whole different ballgame as far as forms, taxes, statutes, etc. An F4 is to transfer (buy)...so somebody else has already made, manufacturered and/or imported the firearm. You can even F4 an item made via an F1, and the new owner has no additional engraving requirements. |

Have your Ps and Qs in order and know the law if you travel through here with an any other weapon or a suppressor. Might be helpful for the informational purposes of this thread to know which of the states not listed in a much earlier post At this time, the following states allow private ownership of silencers: AL, AR, AK, AZ, CO, CT, FL, GA, ID, IN, KY, LA, ME, MD, MS, MT, NE, NV, NH, NM, NC, OH, OK, OR, PA, SC, SD, TN, TX, UT, VA, WA, WV, WI, and WY. Of the sixteen states which do not allow civilian ownership, CA, IA, KS, MA, MO, and MI allow class 3 dealers and class two manufacturers to possess silencers. have exemptions for law enforcement officers While its not a popular thing to admit on this site because some people make snarky comments about "some animals blah blah whatever", some states do exempt individual officers from purchase restrictions that apply to non-LEO edit: based on reading some of the follow up posts, that original list of states needs to be updated edit: Since my post generated no replies, I'll start. NYS Penal law 265,02 is what criminalizes suppressor ownership in NYS S 265.02 Criminal possession of a weapon in the third degree. A person is guilty of criminal possession of a weapon in the third degree when: (2) Such person possesses any explosive or incendiary bomb, bombshell, firearm silencer....., PL 265.20 lists exemptions to the above S 265.20 Exemptions. a. Paragraph (h) of subdivision twenty-two of section 265.00 and sections 265.01, 265.01-a, subdivision one of section 265.01-b, 265.02, 265.03, 265.04, 265.05, 265.10, 265.11, 265.12, 265.13, 265.15, 265.36, 265.37 and 270.05 shall not apply to: 1. Possession of any of the weapons, instruments, appliances or substances specified in sections 265.01, 265.02, 265.03, 265.04, 265.05 and 270.05 by the following: (a) Persons in the military service of the state of New York when duly authorized by regulations issued by the adjutant general to possess the same.

A co-worker of mine asked what are some of the disqualifiers for purchasing / owning a suppressor?
Particularly he was curious if having a DUI on his record from ~10 years ago would affect his ability to purchase one? I suspect it may be like many "normal" firearm purchase laws where you cannot have a Felony or a Gross Misdemeanor Domestic Abuse type conviction. What is the official stance on purchase / ownership disqualification? I had no idea because I have a very clean background. |

No. But, that's doesn't stop a lot of dealers from doing it. I've never waited on a Form 3, and that's using 3 different dealers in-state. Silencer Shop says they have a variance from the ATF that allows them to do it as well. |

I would like someone to talk more about how the supressor actually attaches to the barrel. The FAQ made it sound like additional threading had to be done by a local machinist. A person cannot just buy a threaded barrel? How do QD attachments work?
Use this an an example. A person buys a stock handgun (Glock 17, H&K USP .40, take your pick), and a can. What must happen next to connect the two? Please show pics if possible. |

My 1911 barrel was semi fit Check lone wolf, silencerco, barsto, storm lake, and KKM. For one off scenarios, a gunsmith can make a custom extension for your barrel or in the base of a like a beretta 92, just thread the extended portion This is my beretta

I have a question.
User serviceable. Why would you buy one that isn't? No good options? I am waiting for my first can, so I am not trying to be a know-it-all, but at this point in history shouldn't they all be user serviceable? It should also be listed at the top of the info right under the caliber. Right? |

The power to cause pain is the only power that matters,the power to kill and destroy,because if you can't kill then you are always subject to those who can,and nothing and no one will ever save you.

4 pages of reading and this one hasn't been addressed, nor is it covered on ATF.gov. I live in a suppressor legal state, TX, but am considering a move to another state, CO or MT, also suppressor legal. What happens if I end up moving before approval of the Form 4? |

You’re a resident of the new state officially. Form 4 gets cancelled, get you’re $200 back and start the process over in the new state. |

I've got carbon steel cans that have lasted thousands of rounds just fine because they only get used on a bolt gun and the blast baffle was specifically designed not to wear or peen. |

You'd have to cancel your F4, transfer it to local dealer via a Form 3, then file a new F4. |

A couple questions...
Existing sealed aluminum 22LR can - what is the best cleaning method? Radiant556 idea sounds great, but it doesn’t seem like he likes it for aluminum. New .30 cal can. Will be primarily used on 5.56 10.5-16” BBLs. If the can is threaded 5/8, and I use a break/flash hider as a mount - is the 5/8 thread on the muzzle device? Are the muzzle devices proprietary to the cans? Also, what material would you recommend for the new can? I’m a little concerned about aluminum with the muzzle pressure and potentially stripping threads. I’d love to keep the weight down though. |

I don’t think you’ll find a can rated for 10.5” 5.56 made out of aluminum. As a minimum, the tube and baffles are going to be stainless steel. Some may have titanium baffles to keep the weight down. |

| New to the forum and almost a suppressor owner but need some guidance. I was living in Alaska and purchased a suppressor and sent in my form 4 through my local NFA dealer. While I was waiting for the form to be approved life happens and I had to move for my job to another NFA friendly state. But, before I moved my form was approved and I hoped it would arrive prior to me having to leave the state. So now my approved stamp and suppressor are in AK and I am in Colorado. So what is the easiest wind quickest way for me to get the can? Can my AK dealer ship it to a local dealer in CO and he transfer it to me? I’m hoping I don’t have to start the process all over after having to wait so long once already. Appreciate any ideas. |

If you’re not still a resident of AK, you’ll have to cancel the stamp and start over. If you happened to submit as an entity (like a trust/corp) and still had a responsible person in AK they could get it. |

I've been thinking about dipping my toes in the pool. I read through and didn't see anything on this. Is it correct that there aren't any yearly hassles such as renewals, phone calls, etc. associated with owning suppressors (or SBR's)? It's just a one and done thing... and make sure you keep your paperwork handy? Thanks. |
