We have had a lot of requests for our ambi billet lower parts upgrade kit.  This kit would be for any customer who has purchased an Standard + or Pro Model, who would like to upgrade to semi-ambi.   This kit would include our ambi billet adjustable fire selector.  This is adjustable from a 90 degree to a 70 degree short throw.  The kit would also come with a drop in billet bolt catch that is machined from S7 tool steel and is vacuum heat treated to give you a robust bolt catch.  It would also come with our ambi mag release to give you the option of controls on each side.
