Disturbing discovery

[dralarms]

I have a PLR 16 (223 pistol) that comes factory with 10 round mags, I have always used my 30 round mags in it with no problems. That said here is my problem:

I just purchased a Ruger Sr556 and in order to use my "bench rest" I need to use the shortened mags in it, well they won't fit, won't go in my S&W M&P15a either.

Now here is my question, Are you supposed to be able to use the regular 30 rounders in a PLR 16? The reason I ask is last week I went out shooting (finally) with my son and his PLR 16 kept jamming, failing to extract. I don't think the problem is related but wanted to ask all the Ar guru's. His problem sound slike an extractor problem not a mag problem, am I correct?

Thanks in advance for the help.

Don't have a PLR or an AR, but guys I've talked to said they ran 30 rounders through their's with no problems.

Thanks, so apparently the 10 round factory kel tec mags must have a stops on them to keep you from using them in an AR. No problem. I'll figure out something on that.

Also I have 2 extractors coming from KT. Mine is not acting up (yet) but I figure I might as well have an extractor handy just in case.

Yeah you are supposed to be able to use standard AR mags in a PLR.

I thought as much. Now the other way around will not work for some strange reason.

I discovered this since I was gonna use my plr mags in my Ruger Sr556, well that ain't gonna work:rolleyes:, guess I can always try and site it in without "benching it". All I know is @ 100yrds I hit the paper 6 times out of 30 rounds, of course I guess that's pretty good since with open sights all I could see was a square that was covered up by the front site:screwy:.

Prone unsupported.

It'll fix all your issues.

ROTFLMAF.

You haven't met me but I don't do prone very well, many years of good eating have nipped that in the bud.

LOL. I could but there is not a good place at the range to do prone, they have shooting benches set up and then it's rocks with grass growing through them:rolleyes: .

Sounds like an extractor problem to me.

I have 2 PLR 16's - never used anything but 30 round mags in them and never a problem.

20 round mags are better of the bench or prone (for the young guys)

It was the extractor. Shoots like a dream now. Thanks for all the input:koolaid:
