Product Questions

how do you extend the stock and remove the mag holder?

Referenced product: STOCK-X-FOLD-M4-BLK

The telescoping stock is adjusted with the lever / button on the backside of the stock (the large hole on the rear of the stock just under the Sig logo). We don't have a stock on hand at the moment so I can't check how the mag holder is removed but there is probably an allen bolt holding it in place.
