I do a lot of shooting sitting on a 5 gal. bucket and a 29" Harris Bi-Pod.
The Q.D. connector on the front of the Forend just doesn't work on this long Pod attached to the Ultra. There is a machinest/gunsmith at the local gun show that has a machined combination of the 1/4-20X 1/2" FH screw with the Q.D. All in one. (not cheap but works super)
My question is: on my .243 Ultra the 1/2 length sure look very, very short to me. I get only two turns of thread before the chamfer is in contact with the Forend. The machinist says that the 1/2" length is factory spec. I can see a 5/8" or even a 3/4" on my Ultra. could fit. Do I have a thicker Forend perhaps? Would be interested in hearing from other Ultra owners on the length of the Forend screw.
Wondering why H&R would use a course thread here instead of fine?
Thanks for any comments. DG
