Hi Ed45 , I have a Mech Tech unit for a Kimber .45.The unit works very well but you need a scope to shoot ,mine was a $99.00 from Bi-Mart they helped put it on. The unit is sturdy I just add my 1911 bottom frame load 10 round mag rack the bolt and fire away, lots of fun shooting only down side is a humming sound from the rear of the barrel after each shot a little strange but dosen't affect the shooting.
Easy way to get a .45 rifle.
