Appreciate the input. That's what I was looking for.No,not if it is not "custom". I bought a Foster frame at Camp Perry for $132.00. It has the plunger tube cast into the frame. The regular frames were around $15.00 cheaper.
A standard Caspian slide is $279.00 IIRC. You could get by with $400.00
Of course there are unlimited options which would add to the costs but for a standard Gov't slide and frame that's a little spendy IMO.
