    Hey all,

    So, Im building my A2 upper and ordered my barrel and stockset...

    Barrel came today and to my surprise, it has the triangle handguard cap.

    My stocks have the round!


    I need to swap out the cap... However the front sight has been installed already...

    *Is it just a matter of driving out the pins, removing the FSB and swapping in the round cap.... then slide the FSB back on and tap the pins back in???????

    Can you post a pic? I have never seen a round forearm cap on a mid gas gun. They are all triangles and accept the round guards

    I think it's refering to something else. A standard mid with a delta ring and forward cap should work

    There was a round cap on some carbine lenght rifles, I have never seen one on a mid. I'll see if I can find a pic

    I'm sorry man, I should not have been pokin fun. All the hand guards I have come across will work with the triangle front pan, even if they are round or aftermarket. Re reading that I bet you do need a round carbine pan. I have never seen one on a mid gas system rifle so yours came with what's expected on a mid.

    To change it you will have to pull the FSB, it's pinched behind the front sight and the shoulder on the barrel.

    Midway has the pans avaiable

    Still, the pan it needs is a carbine pan. The mid and rifle pans are triangle

    It's not a huge deal to pull the FSB, well it's not a huge deal if you can get the taper pins out. I have seen some that really had to be fought.

    At any rate, it seems that they use that carbine pan no matter what lenght system you put it on

    Does it matter from which side I drive the pins out

    Yes, they are tapered and will only come out one way

    My experience has always been they come out the ejection port side

    Well the pins came out easy enough and I got the sight block off.

    Just waiting for my round cap to come in the mail... And the stocks of course
