Ah, interesting. Got a 3+ micro about a month ago and mine doesn't have the wobble problem but my pin is super hard to get in and out so maybe they changed the tolerances on stock ones idk.
Very sorry that we ran out of these, we are typically better than this at forecasting demand. No excuse, its our fault. We are making more now (machined in house). With heat treat and finishing/nitride, these should be back in stock in about 2 weeks. Thank you for being patient with us.
Can the wobble affect the bolt? I took my 3+ out for the first time and the bolt locked back after every couple rounds. Either that, or a break in period.
Yes; we keep calling it cotter pin, circlip, sometimes just "the clip"... I think the correct term is "hairpin clip" but its so much easier to call it what its not lol
