I have for sale a new, unfired Mech Tech Carbine Conversion Unit. It is chambered in 460 Rowland, but I was told by Mech Tech I could shoot 45 ACP's in it. Brass cased only. I used to have the 10mm version and I shot .40 cal in it all day long and it was fun and accurate as anything I owned.
Specs can be found on http://www.mechtechsys.com/1911.html
It also comes with a Simmons 2.5x 20 scope never sighted in, brand new with box. This type of scope I have found to be the best for such a small carbine. The reason I am selling is I have gone a different direction with my 1911's and found the new world of AK's.
I had this on a rock island frame and it worked flawlessly.
Any questions feel free to email or IM me.
Price is $325 shipped.
Pics, someone could post if they want to. http://community.webshots.com/user/jaketjcj
