My 1st AR15!!!

[rainman73guns]

Just got my first AR15, its an S&W MP15 sport, havent gone to the range yet.
As you can see from the pictures, I have another complete upper which I plan to use with the MP15. The problem is, I cant take out the FRONT takedown pin. There seems to be a small spring holding the takedown pin so that it wont slide out. There's also a small hole on the ejection side where you can see the spring.

Can anybody out there help me, I dont want to force the front takedown pin which might have some bad results. Help

Take a 5.56 round or a pen. Tap the back of either with your hand forcefully. Should pop out.

Looking at the pin, there seems to be something protruding from the lower receiver toward the head of the pin. Just dont want to mess it up

Range report please...I was giving some thought to buying one of these as my first AR.

As soon as I get some time off, just had a new baby 2 weeks ago. I was looking for an AR for a long time and when I saw this in the Gunshop for $657 i grabbed it. Got some good reviews online.

Detent?

Pic?

 

[rainman73guns]

It's right below where the dust cover is, inline with the head of the front takedown pin

Indent for the pin so it can't leave the lower.

Can it be taken out without messing the rifle. It's definitely on the head of the pin. Any mp15 owners out there?

 

[mopar92]

The pin is designed not to be removed from the lower. It slides out enough to remove the upper. But its captured at the end of its travel so it isn't lost during fieldstripping.

On all 3 of my AR's NEITHER pins come all of the way out, as in completely seperated from the lower. They do, however, slide through to the right side of the lower to allow removal of the upper. They have detent pins that ride in grooves in the takedown pins that keep them from coming all of the way out.

I'm not inherently familiar with the rifle you have, but I can only believe that they are set up similarly. Some rifles take a little "coaxing" to get the front pin out far enough to remove the upper.

Push out the rear pin first then pivot the upper on the front pin. Apply a bit of pressure to the left side of the front pin as you pivot the upper. A little WD40 or CLP helps too. Have fun juggling.

Enjoy your AR. I love mine. They ARE addictive.

Yes the rear pin doesn't go out all the way and I expect the front one doesn't too . I just worried that the small spring holding onto the head of the Front takedown pin might ruin the lower receiver. I'm pushing the rear pin and it slides easily but the front doesn't

It's always rough at first. It will break in over time.

Small spring holding onto the head? Hmmm. Got a pic of the right side of the receiver? I've never seen a pin held captive by a spring.

Can you post a pic?

If it's protruding from lower into the pivot pin, below the head of the pin, on the side where the pin's head is flattened, it's most likey the detent pin (unless S&W redesigned that area). It rides in a grooove in the pin like the one does in the rear pin.

The detent is spring loaded to push into the pivot pin and capture it so that it does not fall out when field stripping.

 

[fivepointstar]

at AR is still new so it may be tough at first. as stated before use a pen or the end of a 223 to push it through.

(if that doesn't work just give it to me)

Congrats. Try tapping the pivot pin out with a plastic ball point pen, or if you are not worried about dings with a cleaning rod section. It is probably just firm because it is new. When you get it out, put a drop of oil or gun lube in the detent groove.
