    Unless you have the spring and plunger on hand you are probably going to order them....do yourself a favor, order them from Brownell's and while you are at it throuw this in the cart for $18.00:

    It makes life a little easier and you are less likely to mar the receiver.

    These are also available, I can't speak to the quality:

    If you follow the advice of an earlier poster and do not punch the roll pin completely out you can easily use a pair of pliers to reset the roll pin and then one single tap with the roll pin punch for final placement.

    I've seen it done with regular pliers with just duct tape wrapped around the jaw; I use some vise grip looking channel locks I got at Lowe's - the jaws slide together parallel as you squeeze them. I use tape to pad the jaws.

    Hope this helps.

    I've seen the same thing happen to three different lowers. The toe part of the bolt catch/release button that the plunger and spring push against will peen out some material from the hole in the lower and prevent the plunger from pushing out completely against the bolt catch. Just pop the bolt catch out and I bet the plunger and spring are staked in. I just used a pick and cleaned up the hole and slapped it back together and it was new again.

    I hope that made sense.

    How so? Especially when none of us actually know what the Ho-Lee Phuic happened? Most AR parts designed to be replaced. Unless we know more about round counts, etc.. it's all just posturing.

    As I read it... it's still working now. It's just unusually loose, but something worth addressing before it becomes a problem.

    You're not chuckling alone.

    Prepare to blame user for running a non-standard modification...miss
    Prepare to blame quality of manufacturer parts...whiff
    Turns out to be a brand that's beyond reproach...stuff happens, fix it and move on

    Yes, that's pretty humorous.

    But to then pretend this wouldn't have gone quite differently, had it been a "bottom-feeder" lower, is freaking hilarious.

    Springs are wear items. No matter if HK, colt or B&T made it. It is also hard to do QA on springs so that doesn't bother me in the least. What does bother me is when I see bolts break at under 3,000rds, ejector pins hanging out of bolts, FCG pins walking, etc.

    As IG said replace and move on.
    I've seen FN M16a2s and Colt M16s even parts fail to include sears worn out, bolt catch broken, take down pins snap off (normally when dropped) springs are a wear out part. If not check with BCM about a check up return. With all that I'm not the holy grail person I have everything from trash ARs to Colt and BCM stuff.
    I'd say you might want to pick up some spare parts anyway for your AR anyway along with 26 inf said. A small spare parts kit good to have to keep one up then not waiting on with out.

    The spring is not expensive or difficult to replace. Replace the spring.

    Inspect the area on the receiver where the spring travels and let us know what you find. The problem could be a burr, a piece of dirt or the spring was weak from the get go.
