I have been wanting an AR-15 style rifle and decided I want a varminter version to keep the prairie dogs at bay.  However, I have always heard good things about the RRA trigger and I want 6 position stock.  Unfortunately, neither Bushmaster or RRA has a varminter with the adjustable stock.  I have been thinking of getting the

RRA Complete Lower Half / National Match Trigger / 6-Position Tactical CAR Stock

I was also wanting a fluted barrel, and so I am looking at Bushmaster Varminter Upper Receiver

This will be my first AR.  I am not sure if this should be  in the general or build it your self section.  But if I get a complete upper and lower, what else would I need.  I assume the two would be compatible.

OR

should I just pick a factory model (Bushmaster or RRA) if I should do this? Which in y'all's OPINIONs is better?  I realize this is a subjective question but I would like to know opinions and reasons for these opinions.  Thank you

My first AR was the Bushmaster Varminter.  It is absolutely AWESOME !  Extremely accurate.  Two stage trigger,  fluted barrel, hogue grip.  You will not be dissapointed with the Bushmaster Varminter.  All you will need is a harris bipod and scope.  You can always change out the stock if you don't like the standard.

Good Luck.

how difficult is it to change the stock?

I changed the stock on my m4a3 with a Magpul M93b.  It's not too bad at all.  Just be carefull removing the stock because it has a couple springs that can possibly go flying : )  

any special tools required?  I know this is probably somewhere in the forum, I am just too lazy to look it up, actually don't have the time right now since I am at work, I also wanted to bump it BTT  :D

to remove the original stock you need a screwdriver.  and to to put the new one on ..   well that depends what you get.

Quoted: just buy the bushy and change the stock...

+1

screwdriver?  where can I get one of those?

j/k  I may be a noob to Ar15s but I got plenty screwdrivers.  thanks for the info guys.

no problem.  any time.

another question, why isn't the varminter barrel chrome-lined like other barrels? and does it really matter?

ARFCOM lore states that chrome lining will decrease accuracy slightly.

    A Bushmaster complete upper costs 725.00 . You can get the whole rifle for a little over 1,000.00 if you buy online. So I think you would be better off getting the complete rifle. You will get a match trigger and a bolt  that is matched to the barrel for precise headspace. The barrel is not chrome lined but it is 4150 steel. I have one, very accurate well made rifle.
