Thinking of building an AR

[Forest]

ok. Did not know that was an issue. I am only familiar with the A2 in the Army and have not seen that happen.

It's not an issue. Most of the guys that I know run them have them on their NFA M16s. Since they prevent pin rotation it's seen as a way to reduce wear due to the pins spinning (still kinda silly if you ask me) on their $10-$15K machine guns. Others use them as a security blanket. But if you built your rifle right, with quality parts then there really isn't an issue - if there was they would standard on Military issue weapons by now.

Keep pulling the trigger for long enough, it will. I got up to about 7500 rounds before my pins started to walk,.

Odds are the J pin in your hammer broke - which means you need to replace your hammer.

Everything's intact, I've had 3 diff't packs in there, and probably also due to me constantly removing the pins to get EVERY piece of schmutz out of the lower when I clean, they started to walk when firing.

I've since modified my cleaning method.

haha i always wondered what that was

Yeah constantly tearing down the lower will wear the pin holes. There is a reason why troops are not allowed to do that. .

Point Taken - 'But my lower still has some specks of goop in there...', I figured that out the hard way. At least it was a cheap and easy fix, KNS Pins, and q-tips for cleaning the lower.

"Overcleaning" is a major source of ARs/M16s lives being shortened. I think this might need to be posted:

15-20 minutes to clean is all you really need. "White glove" clean is neither required nor recommended.

And of course one more..

In the beginning, that would have hit my nail right on the head, with the exception of using power-tools and simple green and correction fluid, thank god I learned within a month or two, the 'white glove' clean was not exactly the best way of doing things.

My cleaning time now is about 5-10 minutes for the piston, and well under 10 for d.i.

I never said I was an expert, but I learn really fast when it's my money on the line.

Awesome pictures.

There is another PS article that outlines the cleaning process AND the new (at that time) no "white glove" cleaning "requirement". If someone has that, please send me the PS # that it is in. I can print it from work later.

I'll check I've got a bunch of the M16/M4 stuff on .PDF

ETA:
I've got the "Complete M16 Cleaning" article from PS 579 in Feb 01 and a bunch of others with cleaning tips. I'll have to check my home computer to see if I have the white glove one.

You should see what I keep on the thumbdrive I wear at work. Unfortunetly it's running out of space so my PS Magazine selection is limited. I have more on my personal Laptop.

BTW any easy way to upload a .PDF here?

Thanks! I guess I'll start another thread to post them as not to derail this one any further.

After all my encounters with Clandestine, I get leary about those type's of comments from the 'AR Guru's', he has somewhat scared/scarred me.

But you guys did help me to get that piston running right, so I got to give you guys that.

Don't most threads get de-railed by page 2 anyways???

I still like the idea of the Plum Crazy lower and they do have a lifetime warranty so it might be worth a shot for 100 bucks.

I bought a S&W M&P lower for 125.00 Stick with a proven design The only reason companies use plastic is because it cheap You get what you pay for

I'm building a budget AR too and picked up a GMMG lower at Gun Connection in White Marsh for $100.00.
