The stock shortening andd swivel mod write-up should be done soon. Don't use the Uncle Mike's flush cup. It's not threaded but grooved and depends entirely on the bond strengh of the epoxy for retention. Grovtech sells the cups but I think there was a minimum quantity required. I just called McMillan and ordered the cups. I believe they are also the OEM manufacturer of many of the heavy-duty quick-detach sling swivels.
I belive these are the Grovtech catalog numbers:
720251 – cups
11902125H – 1 1/4” QD/PB swivel
The key with the flush cup installation is using a suitable stock. The Speefeed solid-stock was perfect for this application, being at least twice as thick as the other stocks. Nothing is hollow here except for the bolt tunnel and a portion of the buttpad area. Most other stocks are comparatively thin and hollow through out, requiring alot of filler material. This is the closest thing to getting a solid wood stock on a shotgun, without the disadvantages.
