Hello Everyone,
I am working on an AR build with an eye towards accuracy. I have started with the following:
Mega Billet Upper
Anderson Lower
S&W LPK
Odin BCG (6.5Grendel)
White Oak Barrel (.243LBC)
FAB Defence Stock
One of the reasons I picked the upper is that it requires "thermal-set" barrel fitting. You have to heat the upper to fit the barrel. I also want to true the upper receiver face. I have ordered the lapping tool from Brownells and while waiting I have done some reading....
It turns out that a number of folks are having trouble using the lapping tool because it won't fit in the receiver.
Would it be appropriate to heat my upper in order to fit the lapping tool?
Thanks.
S.
