"caliber change"

Comments and Suggestions: This is a great kit. I can do a caliber change in about 2 minutes. with ammo sometimes hard to find, I can use any 9, .40 or .45


"Install of the conversion kit"

Comments and Suggestions: (For some reason my message didn't come through completely) The caliber conversion is as easy as knocking out the barrel roll pin, removing the .45 barrel, and putting in the .40 barrel and replacing the barrel (and minding the ejector is in place) and dropping the machined bolt in. It takes maybe 5 minutes. It doesn't hurt to pick up the armorers manual from this site as well.


"Nice change-over!"

Comments and Suggestions: It's nice to have a firearm that converts calibers as easy as the USC/UMP, and thanks to Adam, we have the parts available to do it ( not to mention the machining to semi auto so the bolts fit our semi-autos)
