since this is a thread about AR's i think i'll share what happened to mine last night...
I had just mounted my scope to my brand new RRA LAr-8 (.308) and i thought i'd oil up the safety selector to work it in a little. It was a little hard to flip from safe to fire and back. So i dab a little oil from the top of the lower reciever onto the safety selector and start working ti back and forth. About the 10th time i switch it it does the following.
(BTW, it's not a cheap lower parts kit, it's RRA 2 stage match trigger and LPK)
I'm guessing that its made out of plastic and not a polymer of some sort?
I know to keep costs and weight down on every corner plastic is used but a safety is pretty important. Most likely a manufacturing defect though, but still bothersome.
luckily there is a lifetime warranty on it.
