When I was installing a sling mount on my AR, I had to remove the buffer tube. After putting everything back together, the rear pin won't completely come out (which is good), but it's so loose that it backed out all the way while shooting a couple of times (which is bad). What did I do wrong in putting it back in? Thanks for any info you guys can give me.
 
Thanks for the heads up guys. Just verified and the detent is definitely gone. When I pulled out the pin to the end of travel and flashed a flashlight in there, I saw the end of the spring but not the detent. Makes me appreciate red rifles a lot more lol
 
Open a beer and start crawling around on the floor! good luck!

No chance, but thanks for the kind wishes... Been vacuumed twice since the plate install, just didn't get around to doing any shooting. Got one lined up at Tetragon, though, so I'll swing by there tomorrow. Needed a dust cover spring anyway, so it's not as if I'm making a special trip :)

What? It isn't the rifles fault you drop parts. Maybe you should pay closer attention when you are taking things apart and putting them back together. It's not like these rifles are complicated. I'll take a US designed and built rifle over any communist rifle any day of the week.

What I like about red rifles is that they are simple to take down, more reliable and less maintenance-intensive. I don't own any any more, but I owned a couple and shot them a lot. The reason I switched to the AR platform is that it's a much better match for my sport shooting needs - faster followup shots for higher scores and faster mag changes for faster times. That comes at a cost of more mechanical complexity and tiny parts more liable to go flying. I'm paying it willingly.

You are welcome to your opinion about communism. And mine is similar, whether it's governmental communism or corporate communism. That doesn't change the fact that red rifles are here to stay, are being used all over the world and even south of the border, everybody and their grandmother owns one and a few crates of M43 and/or 7N6.

Yup, one day I dropped a Savage extractor bearing (that what they're called?): anyways, it rolled off my grip, onto the bench, bounced and onto the floor. The cat seen it, I didn't, and I was fast enough to catch the cat before it went in its mouth!

They all have the positives and negatives. One positive of a lot of Red rifles is not caring if you find mud around the bolt. The Black rifles can be too expensive to not panic over that.

Black rifles are more Barbie Boy with all the purdy accessories like purses (MOLLE stuff), fancy belts (X-point slings) and the like.

Red rifles, black rifles, blue rifles... I don't discriminate: it just ain't Canadian!

Try an ACR, some people seem to think they are a little heavy but they don't have all the little springs and pins to get lost when you take them apart. If you don't care about making it non restricted you can have a 12 inch barrel made. I bought mine with a 12 inch and it was awesome, I wanted non restricted though so I sold the shorty and used the money towards my non restricted barrel.
I love mine.

I tried it the day before yesterday and liked it even though I'm still more comfortable shooting my AR, especially when the clock is running.
 
And a cut down spring from a Bic lighter will work as a safety detent spring...I learned this when I had a similar experience to yours while changing the grip! :D

Lol thanks.. Well, I got that sorted out, but because I was troubleshooting a lazy ejection issue, I took the bolt apart for a detail clean (usually it's just a blast of carb cleaner) and found out that one of the gas rings was in pieces. Will have to replace them.. AR's are nice shooting guns, but really high maintenance.
