I’m ordering my Mk.12 from Centurion tomorrow but I’m going to need a few parts to finish it off, namely a rear BUIS and an A2 (A1 might work if the price is right) stock plus the associated hardware–buffer tube, spring, buffer, screws, etc. I prefer the HK-style front sight from Troy so that’s why I only “need” the rear KAC unit. The brand of stock isn’t important so long as it’s a reputable manufacturer and neither is color b/c it’s going to get Krylon’ed sooner or later but it has to be decent physical condition/not cracked/etc…
I put the stock WTB here too since I didn’t want to post a pair of WTB ads–one here for the BUIS and another in the “Furniture” subforum for the stock kit.
ON EDIT: Got 'em both so this one’s done.
