AR15 takedown pin question

The takedown pin on my AR will not budge and I have to loosen the stock and take out the spring and detent to remove the rear pin. I followed the assembly guide over at AR15.com and I am pretty sure I did everything correctly. I put the detent in, followed by the spring, then the takedown pin. I have fooled around with it for about an hour now and still cant get it working.

The upper and lower is CMMG and I used a STAG parts kit if that helps any.

Any ideas?

My RRA was tight when it was new, but it has worked itself in. If it's really tight, I would suggest to check your build, but maybe you might have something out of spec :scrutiny: Really depends on several things....

My bushamster pins were really tight when I first got it. The new Stag lower with Stag parts kit, I just put together isn't nearly as hard to push the pins out. Could be because there is no upper on it yet...

I have the same concern with my bushmaster varminter. I got all kinds of good advised including a nylon tipped punch. I tried to locate a punch but was unsuccessful. I finely went to impact arms and they GAVE me an "L" shaped nylon tool to remove the pin. On the back it says "bushmaster" it works well and is made by bushmaster. I'd get on their website and see if they will send you one.

Make sure your takedown pin detent is in place the right way, that is, pointy end to the slot in the takedown pin and flat end to the spring side.
A light film of grease in the takedown pin detent slot doesn't hurt anything either.

A trick I teach my students is to keep pressure on the takedown and pivot pin (whichever one is tight) and at the same time, charge the weapon a couple times. The vibration is usually enough to break them free without having to resort to jabbing at them with a cleaning rod, cartridge tip or Leatherman and scratch the finish.

My new Rock River Arms National Match was so tight, I could not get the pin in by finger-force alone. Course, with a nylon hammer always in the range bag due to my love of Mosins, who cares?

I just find it humorous that I use the same $2 hammer to beat my $1200 AR as my $89 91/30 :eek:


:D
