Sloppy fitting lower.

[elkbow]

be careful on using bedding compound on the lower if you swap uppers, if you do swap uppers, don't bed the lower, use and accu-wedge or other methods as each upper/lower fit is different

if you use the same lower and upper all the time, two ways of bedding the upper to the lower with bedding material. On method is applying bedding material to the mating surfaces and the other method is to bed where the lug is, where you would put the accu-wedge
