Kabayan, are you planning of getting the Limited or the regular one, familiar lang kasi ako sa regular. If you have the regular, the first thing to go is the mag release, plastic kasi yung stock. Actually, good to go na 'yon after that. If you want to have a trigger job (lighten the pull), i suggest you replace the hammer, sear and disconnector. Tapos replace na lang yung other parts when they break or when you get the urge. ;f
My family (father side) comes from Talisay and Agoncillo. Si Doctabako from Balayan.
