That's what I was afraid of, mixed reviews. For the price difference I wouldn't expect the L&R quality to be that of the new Kibler I have. However, as far as I know no one else but L&R makes a back action lock. I suppose I will see if I can repair and tune the old shotgun lock I have on hand and if that doesn't work I'll buy the L&R. The reason for the back action lock is to build a bench copy of my ancestor's original. There's a thread about a Joe Meek rifle build from 2008 here but I don't know how to attach it. His rifle, Old Sally, is pictured in Hanson's book The Plains Rifle and it has a back action lock. It's probably the ugliest rifle I've ever seen but I sure enough wouldn't say that to Ol'Joe himself!
