thanks for all the advice folks. i think i wil go with the stevens, that way i can practice my gun smithing without the worry of screwing up an expensive gun. i do have some questions regarding terminology i don't understand. bear with me, as i'm pretty new to the whole gun upgrading/modification process.
MOA - does this mean Minute Of Adjustment? what exactly is it?
bedding the action/barrle nut - what is it and how do i do it?
free floating - what is it and how do i do it?
tuning trigger - i'm guessing this relates to how much pressure is need to pull the trigger. how do i go about tuning one?
opening forend - mysticplayer mentioned this, i don't fully understand what he means.
OAL - what is this? i'm guessing it relates to the size of the cartridge.
inserts on rings - what is meant by inserts? are these a line that sit between the ring and scope to reduce impact?
thanks alot for the info. it's real useful.

i may have to try and find some junker rifles to try some of this stuff on. i have yet to read mysticplayer's articles, but are there other links/sites that have a "how to" section of this kind of stuff?
