    I just wanted to know if the 5.8" D cell Titanium tube that I am using on my Glock 17 can be used on an 11.5" AR pistol. It is bored for 45 cal.

    Depends on caliber of the AR, if 556 no. You could use it but it will not be effective nor hearing safe.

    Thanks for reposting Weber! This is a great thread.

    Question......I made a can for my 22. If I screw it on my SR22, it goes on extremely tight. When I take it off the pistol, it is on so tight that it unscrews the threaded barrel adapter. Even if I just test it out on the barrel adapter without it being attached to the pistol, I have to use the small wrench to unscrew the adapter for the can. I just twist the can on hand tight, not even putting much pressure at all on it. Any thoughts?

    If you plan to leave the adapter on the pistol, locktite or rock set it on. It will keep it on the barrel, I prefer locktite as its easier to remove later if needed.

    I thought about that, but in order for me to remove the slide for cleaning, I have to remove the adapter.

    That's why I like loctite, it will hold retention but still be removable.

    You could also try some high temp anti-seize on the thread adapter but it will still tighten up.

    I'll be firing .223 occasionally 22lr on it. Will it do?

    On the other hand Legally can I have an extra endcap with a smaller bore or not?

    I would not waste my money, go for 7.6" at least for your application. You can not have an extra end cap or thread protector legally unless you secure the internals without the ends holding the stack together.

    I do have solutions for that but they require extra work.

    Thanks for the quick reply.

    I'll do the path of the 7.6 then.

    Weber,
    What is the recommended length for a 16" AR if I intend to use .223 and .556?

    What is the measurement for the freeze plugs for the C cell tube?

    Have you built a B cell suppressor? If so did you use the Freeze plugs at SDTA or does NAPA Auto have them?

    556/223 is almost always a minimum of 7.6, SBR's need that or longer stacked with plugs.

    I'm at the Ravens game right now but I can get you the measurement on the c plugs later.

    I have a B size for pistol, you can use the SDTA plugs or a Napa plug, I have the number at home.

    Not sure what you mean by secure the internals but Military Arms Channel had a pre-production Griffin Universal suppressor. The internals looked like they snapped together but it definitely came with different end caps as well as 1/2 x 28 and 3 lug adapters. There was also an extension for rifle applications

    Firm 1 users are not the same as a manufacture. If the end caps hold the internals in place, you can not have a spare or extra end cap.

    Would that work on an SDTA tube?
    Short answer is yes.

    Long answer:
    I own a gemtech GM-9 and also bought the fixed mount for it.
    I built a D cell tube using SDTA parts and have a thread adapter at one end where I attach the LID. Both the gemtech LID and fixed mount directly thread to the thread adapter.

    If you build a B cell tube the 3-lug mount will directly thread to the tube. But in this case it would be holding the baffle stack in place which legally makes it part of the suppressor. In this scenario I'm not sure if you can legally swap extra mounts. Hopefully someone can enlighten us on this.

    Has anybody had issues with a Gemtech LID not screwing onto SDTA's B tube? Their end cap screws on perfectly but the LID absolutely refuses.

    I seen a guy post the same question on the SDTA forum, maybe it was you?

    Besides the post there and yours here, I have not heard that. I would assume that since SDTA end cap threads all the way it's not an issue with SDTA's tube unless it's not threaded deep enough. Measure the threads and go from there.

    Ti SD Tactical tube on a 300 blackout. We don't really know if it was the engraving or how the suppressor was used.
    The consensus on the form 1 facebook page is it can't legally be fixed.
