Welcome to the forum TheGermanGuy, and Swede. I installed 2 Volquartsen match hammer kits, in the 2 rifles I'm building. It cost $31, and reduced trigger pull from 7# to a smooth 2 1/2#. Just drop in parts. Easy to do. I also installed an auto bolt release, I paid $9.95. When I compared it to my stock release, I said I can do that. Just ground out the hart shap into an oval shape. Did it for my brother 2 days ago. When he saw how well it worked he looked like . I also installed an extended mag release. Works really nice, and a WeaponKraft Bolt buffer. ($5 for 1. I ordered 3 for $10. Really quiets the action, and prolongs the life of the receiver. (Ya know, a bolt hammering away at a steel pin in an alum receiver) Will probably get a bug tunner to tune the barrel to the ammo. I really like this stuff. Have already gotton some comments at the range. Like "You mean you built that rifle?"
