So I recently bought a pre-upgraded Bar-10 that someone had put pretty much a full run of ASGI parts and a laylax piston into and predictably the m170 ripped a crescent moon divot straight through asgi's "reinforced" piston sear. Now I didn't pay any more than I would've to get a stock one shipped here so while a Zero, V, or M trigger is way out of budget thanks to a speed trap, and since I'd never get a fair trade value for that much expense around here, I'm still comfortable putting some new (quality) sears in. I've got the stock parts still, actually I put the stock spring back in until those pushups start helping, but I'd obviously like to be able to run the 170. From what I've read in order to pull that off for anywhere near a reasonable number of shots I'm looking at Deepfire for maybe a thousand or so and some have argued that PDI, Laylax, or especially Daiki's will last for ages. I can't find any Daiki sears/sets, but I have found both Laylax and PDI 2nd sears as well as Deepfire, "MAMA" and SHS sets. I don't know anything about the last two and I'm not sure whether Laylax's PSS10 or PDI's Reinforced piston sear would be stronger. I'm also considering breaking out the dremel and finding a piece of really hard steel to epoxy onto the face of the ASGI piston, but again I'm not sure what I'd need to stand this kind of friction and pressure. So, anyone compared both sets of sears, know where I could find a Daiki or tried a DIY solution?
