SAAMI FB is .080” in the 22CM. FWIW IMO optimal FB for the 80’s is .120 and for the 88’s is .170. Can or will non optimal still work? Yes. 88’s in the .120 will have the base of the shank right at the neck shoulder junction.It should be fine. Sammi fb is .120 and I’ve ran 90smks with an .080 fb without issue. The BS is just seated slightly below the neck/shoulder junction.
