About a year ago I traded some gear for a milsim a5. The marker looks a lot like the a5 in this picture.

From what I have found it is an older version of the Ops Gear G36C kit. On my marker I do not have the g36 folding stock but instead a 3 position CAR stock. My question is what would a rough price be for the
-g36 rail
-g36 front grip
-g36 mag and attachment
-CAR Stock
