[ARCHIVED THREAD] - SDTA muzzle device compatability

Posted: 1/26/2017 9:30:52 AM EDT

Alright, I was sitting on a form one and had not ordered parts. I have SDTA flash suppressors on more than one AR (one pinned and welded) I already have one SDTA can built.

Is there any company that does parts similarly that will interface with the SDTA muzzle devices?

Chris of Diversified Machine built a couple for the people but not sure if we will do more (it would be a long wait anyways) b/c he is so backed up with his own parts. The ones I saw for were people that had his tubes already or to fix alignment issues for the SDTA parts (most of the ones in the shop measured off around .060" at 10"). I would use Griffin parts for the new builds, the brakes should be easy enough to resale.

I know this post is old, but is this in reference to their ATF issue?

Cross hair custom, or you can send a copy of form 1 to sdta and they will sell you parts.

Your better off cutting your losses and going Griffin's setup for future builds. Or direct thread.

Few have had bad luck with crosshair including myself, and a buddy said sdta said no to selling him a tube with an approved f1.

Aww, we're buddies

But yeah SDTAC told me it's a no go on selling tubes or end caps even with a form 1. I would not do business with crosshair custom again.

I desperately need a replacement end cap for my SDTAC tube; I don't think I drilled the hole centered.

Anyone know where I can get one that will work?

Due to legal reasons, I won't advise you to replace your cap. However, if I were building a 1.5" solvent trap for cleaning that required a 20tpi end cap, I would probably use one of these..

and probably have it sandblasted for $5 more..

I have the same opinon has the above poster. I don't think most people are aware SDTA will sell end caps and adapters via phone in order without a copy of the F1 (subject to change but they posted that yesterday). Rusty services can probably fix your current end cap, he is pretty reasonable but will require a copy of your f1. If you want to try to correct it yourself use a diamond drum in a dremel (or a end mill in a drill press) to enlarge the hole so that is perfectly centered, then use a ball nose end mill in a drill press to re-drill it. This will leave it slightly oversized but many commercial cans come like this (its not uncommon for a 5.5.6 can to have .275" baffles and .300" endcap. If you need to borrow bits pm me.

SDTA still sells a solid cap under MOUNTS- "no center threads"

You're welcome.
