i originally started out to build an A2 but i am seeing parts for the A1's. I really like the very first AR's, the A1 since that is what i shot in the military. but I don't know if I should up grade to some of the A2 parts.
i found this complete gun but i am not sure about the 1:12 twist. most barrels i see are either 1:7 or 1:8.

i like the A1 rear site as that is the one i used in the military, very very long ago, but i don't know if it has any disadvantages over the A2 sites.
i have also found the uppers with NO forward assist. cant remember what the one i used had or if it is that big of a deal to not have it.
i found the original style hand guards too.

i would like to be able to shoot either 223 or 556.
i have also considered 7.62
i have some concerns about building the upper.
the gas block concerns me a little. i read somewhere about the "venting" but i cant find where i read it.
i found this tool kit, i know its out of stock but what do you think.

i want colt for the BCG
i also want either COLT or ARMAlite for the lower just so it has the name on it.
rock river arms trigger.
anything else or any suggestions.
i don't want to mix parts that wont work.
here is the site that got me interested in build my AR instead of just buying one.

i had considered one of the rockriver arms national match guns like my brother has but he has added weight in the butt to balance it and i don't think i want a heavy gun like that plus i am not in to match shooting like he is.
