Did you lose your GST-9 pins while working on a new build? Not to worry we have not only got some spare parts for you, but an UPGRADE. 

The 80% Arms GST-9 Replacement Pins include 4 steel pins which can cover the ones that you may have lost from your initial frame/jig purchase. Your new steel pins will help increase tolerances, reduce pin walking and overall stability of your GST-9 frame. 

Two pins are for the grip module. One pin is for the B2 hole which is the frontward hole of the front rail. The last pin is for the B1 hole which is for the rear rails. 

*Please note that this does not come with the trigger pin which goes into hole 'A' in the rear of the front rail section.

For more details see the GST-9 MOD1 instructional guide.
