Jewel AR Trigger upgrade

[fastshooter03]

I don't know how many even use these anymore but After a crappy time out with a 22 conversion upper on an old lower I found out you can replace the weak factory Jewel hammer spring with a normal or XP GI hammer spring for faster lock-time and heavier FP hits without an increase of pull.

I used the KNS anti-rotate pins with this mod to get rid of the Jewel pin retainer thing.

Just slip the left spring leg on the outside of the hammer spring sprocket thingy and the right spring leg should be clear.

Hope somebody can put this to good use.
