Thread: Colt M4 vs. Rock River???

any opinions on which is better? or are they both close in comparison?

My agency has issued both. The Rock River triggers are about 200 per cent better than the Colt's. That is about the only difference I can tell.

I own a Colt and I pleased. I do wish however I could fix the trigger for a decent price. Go with the Rock River. If the price is the same then theat would be my choice.---

I'd go with the RR. You can't beat the National Match 2-stage trigger. The down side.....be prepared to wait if you order directly from RR.

Go RR!

I have mentioned this before and will mention it again. Colt civilian lowers and uppers cannot be mixed and matched with uppers and lowers from other makes as ALL of the other makes are capable of doing. This makes putting a carbine or match upper on your Colt lower impossible because the take down pins are of different sizes than standard. Colt LE weapons do not have this problem. Buy the Rock River, or if you are interested the the best possible set up check out Patriot Ordnance's P-415/16 models. They are building clones of the HK version of the M4, a M-4 with a gas piston operating system that has none of the mess of the original M-16/AR-15 gas system.

You may also want to consider the Bushmaster. I have one and it beats myu firends Colt 6920 hands down. I would like to look at the RR but have not been able to get my hands on one.

I would go with a Colt LE 6920 and I'll tell you why. RRA guns are great, I've got buddies that have one. I'm probably going to be buying one to add to my ever increasing collection of AR's. However for a first gun I don't think that you can beat Colt, particularly if this gun is going to be used for duty. RRA uses a 1 in 9" barrel twist as opposed to Colt's 1 in 7". The 1 in 7" is superior for the heavier weight 5.56 rounds like the excellent 75 grain Hornady TAP. All Colt barrel, bolts and carriers are proof fired and then magnetic particle tested. I believe that all RRA barrels are tested as such, but not the bolts and carriers. Also although a Colt trigger doesn't feel as nice as the two stage RRA, RRA's two stages have had some issues for duty weapons. It is a little complicated and not as tough as a KAC or Giselle 2 stage trigger. As for getting a better trigger on a Colt, that's easy go with a single stage Accuracy Speaks unit. Wire EDM finished and polished and then hardened all the way through to give a smooth trigger pull while still maintaining the correct metal treatment and hardness. Finally all Colt LE gun barels are chrome lined, whereas it's an option for RRA. Colt LE guns do use non standard fire control pins, so you can't drop in an auto sear, but frankly that is really not an issue for all but a very few people. Finally even the non LE Colt guns now use standard size takedown holes, they may not have mil-spec push pins but the hole sizes are the same and all new lowers and uppers will work with any other brand. Again this is in no way a knock on RRA, my next AR is going to be an SPR MK12Mod1 upper built on top of an RRA lower with Giselle 2 stage trigger. However for a first AR the Colt will have additional quality control steps that the RRA doesn't have and give a little more piece of mind. Oh yeah and strictly subjectively, I don't think there's a better looking roll mark than the dancing pony. Check out the website that includes AR15 in its address for more information than you might want on AR15's of all kinds. Good luck.
