Does anyone have any experience with theese?

Id like to hear the good, the bad, and the ugly..

Here's some history trivia on the Watson upper.

It was designed and marketed by Dan and Jen Franklund in 1999.  They would sell you the barrel extension and the bolt for $150 or so and with a $150 surplus Ma Deuce barrel, you could assemble it into a 50BMG upper.  The parts came with a serialized binder full of detailed instructions as well as photographs and blue prints of all the parts.  I have number 8, dated June 6, 1999.  The Company was called D&J's Habitual Tinkering in Bismarck, North Dakota.

I actually never received the bolt, only the information with the barrel extension.  The bolt was permenantly back ordered and never arrived.  I took the barrel extension, which is actually the receiver itself in this application, and built it into the Tromix 50BMG over-the-shoulder LAWS rocket style rifle which I sold a couple of years later for $400.  Even at that price, the thing was for sale about 6 months before it sold.

The Watson unit works fine, but it is a pain in the ass to break the gun open and unscrew the bolt after every shot.

I wanted an AR upper type. I looked at the Watson, until I understood the screw in bolt system.

I went with a Ferret, pure bolt and upper.

So are you using a standard lower or the ferret lower with your Ferret upper?

Regular ar lower. Minus a few of the parts (bolt catch and take down pins) and added a special heavy hammer and heavy hammer springs.
