Phosphate extractor > chrome extractor. More friction (grip) between the phosphate extractor and case rim for more reliable extraction.
I run fully chromed plated BCG in all my serious use guns, never had an issue with extraction due to the plating. US mil never listed that as an issue when switching from chrome (cost motivated). Sounds like an excuse to cut corners / costs. Why not supply the fully chromed plated BCG and if some customer has some unfounded concern about the extractor, he can buy one of the cheap and easily available parked ones out there.
Also, no one in the retro community is going to buy that chrome BCG if the extractor is parked, as it is not historically correct.
No worries, just mention in the order comments that you want the extractor chrome too and we'll do one of those instead. The cost of chrome vs parkerized for a small piece like an extractor is negligible, so we're happy to do either.
From our market research the parked extractor is what a lot of folks desire, but I understand there's a market for both and can adjust as needed per the customer.
Where's the chrome extractor? Buy this exact same microbest BCG, but with ALL chrome parts at Primary Arms instead.
