Hi, I have an M&P-15 ORC that I really like. Since I live in NY, the ORC was the way to go. It comes with a pinned collapsible stock. I would like to change that for an A2 stock. For this rifle, do I have to get a new buffer tube, spring, and buffer?

Thanks.

If you want to use the A2 stock you will also need the spacer for the end of the buffer as well as the screws.

Yes - you will need a A2 rifle tube, spring & buffer.

It's a easy job - You can get the whole kit for around $65.00-$70.00...

PK Firearms - fixed stocks

You probably will also need a AR Armorers tool (or a friend with one), to remove CAR stock tube.

Take care,
Bob S.
