All FFL holders (not including C&R) supposedly received this letter. Spoke to one of our local mfgs/FFL's, and they got their letter.

WSP may have lost more than one item. If anything, the lower/lowers has been scrapped and the important "happy switch" parts were moved to a different host lower after the all important 3rd pin hole was drilled for the auto sear, using the original as a jig.

This is only conjecture, but it would appear that something along these lines has occurred. Still doesn't warrant a fishing expedition and compromising all of the information of legal buyers.

The WSP doesn't have an FFL, to my knowledge, because they use a number of individual FFL's to purchase items from, including a few that I am acquainted with.
