Rock River Arms, Bushmaster, & DPMS are all quality made entry AR platforms. Of the three only Bushmaster uses 4150 ord steel chrome lined barrel's, which I believe (if memory service me correctly) are made by Lewis Machine & Tool (LMT). Any of those three manufacturers rifles will give you years of dependable service & all three companies have great customer service.
On the higher end of the market is Lauer Custom Weapons, Wilson Combat, & Les Baer. I don't use Colt products unless a customer requests them specifically. This is mainly due to personal reasons but I have noticed a decline in their customer service and quality control over the past 10 yrs.
The RRA elite car A4 is over all a descent entry level carbine. It has a Wilson barrel, NAT MTCH 2 stage trigger, removable carry handle, forged upper and lower receiver. On the negative side it dosent have M4 feed ramps, look over the telescoping stock real well before you buy it. Ive seen alot of play in some brand new RRA 6 position telescopic stocks, it has a fixed front sight, and the carry handle that it comes with will be tough to co-witness (in the lower 1/3), or it will seriously raise you cheek to stockweld. An A2 flash hider, (there are much better designs on the market). If you go with it I'd recommend the following things
1. Lose that carry handle (put it on e-bay for $30 less than RRA sells them and recoup some $.
2. Get a Troy or ARMS rear BUIS.
3. Get an Ergo grip. (you will appreciate the difference if you use it a lot)
4. If the stock becomes loose or rattles a lot replace with a Magpul M93A2 or M93B, or if you like the M4 style get one from Bushmaster or one from CMT.
5. Get a YHM Phantom or Vortex flash hider
In my personal opinion buy a lower receiver & build your own so you will get exactly what you want the first time (barrel length, flashider, upper receiver, bolt carrier group, trigger, stock, & sights) set up to my personal preferences. Dont get me wrong there is absolutely NOTHING wrong with that rifle. It will be accurate, reliable, and a lot of fun to shoot. Its just after you use one long enough you know what and where they need to be tweaked to add a little extra comfort, durability, and longivity. If you ever have questions on setting up an AR or about aftermarket parts for one drop me a line.
