Short stroke on new build

[High_n_Dry]

The Wilson is much better finished and is Nickel Boran vs the PSA which is DLC finished. Otherwise everything else on the PSA seems ok.
The Wilson bolt does run smoother. When the PSA hits the bottom of the magazine follower there is a definite catch.
I think that the Wilson is just better machined with likely tighter tolerances and the NB coating is pretty slick.
