    Sticky safety selector switch in new build

    I just assembled another Spike tactical lower with the spikes enhanced LPK. For whatever reason my safety selector is a little gummy. It requires a pretty decent follow through with the switch if you know what I mean otherwise it’ll be stuck between safe and fire. My other spikes is smooth as butter as well as my other 2 ARs. I took the grip off and re assembled the switch with the hammer forward and safety on fire and it’s still pretty stiff. Any pointers?

    I put a lot of oil in the detent slots. You can try another detent and/or Safetey too.

    If you have a rotary tool with a pointed end cratex (or any rubberized attachment with bullet end), that should work well in the slot for the detent. Pretty much impossible to screw it up. Perhaps a nice polishing of the detent end will suffice. Grease.

    I’ll try dropping some lube where the detent is and re do the safety again. Detent drops in perfectly. If that doesn’t work only thing I can think of is I grabbed the wrong spring but I don’t think that’s even it. I’ll give it a try again and see. This is the only time this has every happened to me on a build.

    I've had a bunch of mushy selectors over the years. My house gun is so crisp, it's almost too noisy for that bump in the night.

    I had a gummy selector recently. Put a tiny bit of white lithium grease on it when oil didn't work.

    Oil runs off use small amount of grease on the safety detent tip.

    Check the depth of the hole in the grip it may be shallow and causing too much tension on the spring.

    I’m a dummy. Put the wrong spring in. Swapped it out for the longer spring and all good.
