Upgrade is to get rid of the orange disc use. From what I've read it makes it a much cleaner breach area

I sure wouldn't change mine...Those discs are easier to grab then the straight 209 primers and to remove, just open the bolt and drop in your hand...My brother has a 209 Wolverine with the red disc and they are more of a pain to take on and off than the original disc...

I can load the Lehigh NFPJ conversion every bit as fast AND i dont have to install them in a FPJ first or every buy anymore of them.

Sure it takes practice but it is quite easy. Comparing it to a Wolverine FPJ system isn't a fair comparison at all, a DISC action is totally different and any system works fine if you prefer it. I prefer 99% blowby free and far less cleanup. 100% ignition with BH209 is a nice bonus too. The Lehigh conversion requires an Extreme type bolt so you can have the best of both within a minute or 2.

i would be the first to admit that knights primer carriers are easier to load with gloves on but i really like inlines that are blowback free so i just take my glove off...karl

With the Lehigh Conversion - way cleaner!!! Check with Cayugad he changed from the orange to the Lehigh conversion....

To be honest with you all... when i first got the Lehigh Conversion - i had already decided that i would shoot the range with it but when it came to hunting i would switch back to the FPJ - did not happen - you get very good at dropping the primer in the adapter even in the cold with a moderate thickness glove. Then as Breecplug said carry a couple of extra primers just in case you miss.

With the MK-LK-wolverine-Big Horn type gun - I just use a brass capper - works great....

Tell your brother there may be a change coming.... for that series of gun.

Sabotloader, is Lehigh making a conversion kit for the Wolverine also? I have one that shots great, but the blowby using BH209 is real bad.
