I've been itching to start another Form 1 submission, and want to keep it compatible with my Griffin mounts.

I know the mount from SD Tactical is out there (on closeout), but who all supplies the "D Cell" size tubes (Ti preferred) and undrilled end caps?

I think the threading is 1-7/16×20

I haven't looked in a while, but I think MMW still had some available.

Wanting to swap mount and cap on my old "D" F1 build.
Wasn't sure where to pick anything up that wouldn't add me to a list nowadays.

You can get mounts here: https://www.reardenmfg.com/product-category/thread-adapters/
I'm not sure about end caps tho
Edit: just saw you have griffin. I don't think Reardon does that style.

@ECCO_Machine

Awesome, I ended up shifting away from the Form 1 idea for now, and bought (or paid for at least, now time to wait) a factory can through the Silencer Shop promo.

I took a look at your sight, and I'll be picking up one of your Griffin XL Bravo Adapters after the holidays!

Looks like I missed Black Friday/Cyber Monday - Any chance you have an ARFCOM coupon code you guys offer?

Does anyone make a 1.625 OD with 24TPM to HUB adapter? It seems like the max size anyone makes is for the D Cell.

I ended up making one for my whisper suppressor because I couldn't find one for sale anywhere. No idea why they are so hard to find. I guess not too many people building 1.75 tubes.

Not sure what size the 1.625 is, but ECCO has both 20 and 24 TPM options in "D Cell" Adapters

I'll reach out to ECCO. 1.625 OD is 1 5/8ths if I recall. Just a touch bigger than D Cell.

XRT Engineered has a couple options for D cell tubes, albeit they are 304ss, but they are priced reallly low. They apparently did a small batch while setting up equipment for the 17-4 tubes of which I am waiting for
