If you have ever had the pleasure of using the quick release (pull-pin) bolt release on any of the newer D.I.S.C. Rifles, and then have one of the older Allen head screw models you will know what I am talking about. I have an older .45 cal 1:20 twist D.I.S.C. barrel that had the allen head screw, I have been spoiled by the newer quick release on the newer Eltreme and Elite. If you are shooting the new NFPJ conversion shooting heavy loads, you will get an occasional stuck primer that swelled a little more than the rest. If you get a stubborn one that doesn't want to drop out, it is a pain to get and Allen wrench vs just a pull on the pin. This could really be a problem if you needed a follow up shot while hunting, and you didn't have an Allen wrench with you.
I ordered a couple of the "Quick Release Bolt Screw Assembly", Part # 008462 from Knight about 10 days ago. Next, I needed to find a #2 drill and a 1/4-36 tap, which a very nice gentleman offered me the use of, and some insight as to performing the operation. I just hope to be able to return the favor in the future. The drills and tap arrived in the mail, and I was able to make this conversion today.
This is what I started with, for those that are not familiar with these rifles. Notice the Allen head bolt that requires two full turns to back out far enough to remove the bolt.
Here is a shot of the hole and the tools to get the job done. Notice the Allen head bolt on the left and the new quick release pin on the right.
My el'cheapo drill press isn't the best, but it was a gift so I guess I can't complain. Next I needed to drill the hole to accept the 1/4-36 tap. I did this in a 2 step operation first using a #3 drill, then followed by a #2 drill to get the correct diameter hole for the tap. After drilling & tapping I cleaned up the oil and chips. There was a very small burr on the inside of the hole which I removed. You will need a 1/4" socket to install the new quick release.
Here is the final product, I'm happy to report it is a perfect fit.
And for the moment of truth, with the bolt installed. Very happy with the way it turned out.
I am not sure what Knight charges for this conversion/upgrade, but whatever it is, it would be worth it. I think RT just sent his in IIRC, he might be able to tell you. If you have been on the fence about sending one in to Knight, you might want to do it while it is still being offered. Hard telling how long they will be offering these services, or if they even will be offered after June 30th?
