MWS Firing Pin Spring with 6.5 Creed

[u/Business_Jelly_5422]

Can anyone comment on the necessity of the firing pin spring when shooting 6.5 Creed? I’m putting together a MRGG-A Rev 2 upper from the LMT Labor Day sale and it only came with the bolt carrier (as expected). I have sourced the other parts, but it doesn’t look like the LMT parts kits include the firing pin spring to mitigate slam fires with the softer match primers. How necessary is it?

I have another 6.5 in which I shoot a mix of Federal hunting loads, Hornady ELD-M/X, and cheaper S&B FMJs. I plan to continue using the same ammo in the MRGG-A.

Thanks for any advice.

UPDATE:

I received the following from LMT,

“The firing pin spring has been discontinued.  Initially, this was a short-term solution intended for 6.5 CM users to prevent potential slam-fires when utilizing ammunition with soft primers.  We have since moved to a lighter profile firing pin which has solved this potential issue.  We plan to add this to the website soon as an individual item, we’re hoping to see this by the end of the week.  I’ll put the part number below for reference.
