CMMG bolt carrier.  "The pin" does not look like the many Youtube videos I downloaded.  How do I get this thing apart?  I'll post pics if needed, but I haven't been able to take this thing apart.  Thanks!!!

Firing Pin Retaining Pin?  Or, Cam Pin?  The cam pin doesn't turn 90 degrees, like on the AR15...  if that's it.

it doesnt use the same pin as an ar15 so thats why it might look different to you. it is the standard dpms pin just push it out from the sloted side with a small punch or screwdriver.

I broke it!  New retaining pin will be here Monday.  No shooting for me this weekend.  How often do you guys clean the bolt carrier anyway?

Firing pin, bolt carrier, etc...  I assume that you're being funny and don't clean it that often if ever???  I'm new to the LR/AR and was just trying to understand how my gun operates.  These are the videos that got me in trouble:    and this one:

I took the time to watch the cleaning vid,as a civilian without formal training was glad I was on the same page as the youngman.The function test,I do the hammer fall,didn't do the holding back on trigger after charging do reset then drop hammer but I will from now on.I will do more function clean and try to be less anal on cleaning,should cut down time quite a bit :) .Great link thanks brother now in search of chicken biscut,biscut. :D

My apologies gsmopar bro...that was geared more towards unforgiven anyway.

 

I clean maybe every third range session...if I'm shooting a LOT.

Please post up some pictures of how your carrier is different. That first video is my video, and I apologize if it caused you to commit any error.

The 1st video is my carrier and it wasn't the video's fault.  The Retaining Pin just wouldn't come out.  I forced it out with a punch and rubber mallet.  Once it was removed, and I could inspect it; it looked slightly tweaked.  I cleaned the hole and inspected before attempting to re-insert the pin.  When I tried to put it back in, it didn't want to seat fully, and I knew that something was wrong.  Juding from the comments on Midway USA on the product reviews, this appears to be fairly common.  When I removed the pin the second time, one side had sheared.  I have about 25 rounds through this gun and disassembled the bolt carrier more to see how it is done.  This appears to be a good part to keep on hand, but in the current environment Midway limited my quantity to 1 on the order ($4.50 part + shipping...). 

 

Link to the Midway order, read the reviews:  http://www.midwayusa...in-lr-308-matte

The new pin arrived today.  It slides in (and out) without any issues.  I'm back in business!!!

 

I also scored a couple more 20 round mags and some ammo!
