A customer purchased the project sovereign 1 that was listed on the site and asked if I had a replacement ram bolt. I checked around and I found one of the sov 2 stainless ram bolt collars.
These collars are much more sturdy than the stock Sov 1 collars because they are made (cast? hard to think they could mill these) from stainless or a nice looking steel and position the outer oring slots to the outer edge of the collar.
On a sovereign 1’s brass collar the exterior orings are positioned right next to the thumb screw slot with ends up deteriorating after a short while.
In the attached picture you can see the Sovereign 2 stainless collar (new) next to the heavily used Sovereign 1 brass collar that is original to this marker.
