Lapco Barrel Thread Adapters - Bore Size?

[Hooptie]

Hello, I am looking for the bore size on a Lapco Spyder to Autococker thread adapter. Does anyone have any experience with Lapco barrel thread adapters?

I sent an email to Lapco directly, and had no reply. Also a 'google' search showed several McB responses, yet all the links are to the old forum and are no longer active. Thank you.

.684 iirc.

I've got one... Lemme snag the calipers on the morning after I get out of bed

I've got .688. Measured 4 times just to be sure.

Yeah it's definitely on the larger side. The one I'm selling is sized the same as the Sanchez Machine barrel I have, which is .689 or along those lines.

Not sure of the bore size, but I threw all of mine out. They broke paint like crazy. The same barrel would work fine on the the gun it was designed for, but if I threw the adapter on it was a complete mess every time.

Weird... Was getting that with the super barrel when we there the python adapter on there too. Not getting anything like that with this lapco yet... Yet...

Hi Folks, I purchased one on eBay and the measured bore size is around .684. I'd prefer closer to .688, especially if I were to use this on a semi. For now I'll give it a try on my pump. Thank you to all the contributors for your feedback in this thread.

The Spyder barrel-to-Cocker-gun-thread adapter I had fifteen years ago was .688", as was the inverse adapter. Both of mine worked great.

Also curious about these. I have been thinking of gettt a Spyder to mess around with but would want to use my Stella kit. Antoihave experience using these adapters with barrel kits?
