Dear friends.. I have some questions about Tapco AK parts.. hope dont mind me asking. As im new to AK. Seen Tapco products but i dont know what these are or the functions. 1. Retaining plate. 2. Gas piston 3. Grip screw & bushing. Should i change those parts? Improve its performance? In Glocks, most of the aftermarket parts are meant to make our life easier. Just like extended slide level, ext slide release, ext mag release etc. So please educate me about AK. Currently im still waiting for my CIA Romanian Wasr AK47 from impactguns. Will be receiving it next week. Thx for the inputs. Maybe please throw in some ideas of what parts need to be replaced or upgraded beside the furniture. Thank you!
