Chrome is an essential upgrade if you want the most reliable weapon. Chrome enhances reliability, eases in cleaning, extends the life of the barrel by almost twice as long, and protects against corrosion.

Both are good guns though I have have read negative comments about DPMS Quality Control. Like most AR manufactures Rock River does not make any of their parts, they just assemble from parts. Most of their parts are supplied by CMT except the barrel which are made by Wilson Arms(not Wilson Combat). CMT (which owns Stag) parts are used by many manufactures, including RR, S&W, Colt, CMMG, Bushmaster and a few others. In addition their are many other suppliers who make smaller parts such as DPMS for lower parts, LMT and BCM for BCG and a host of others that make lower and upper receivers and barrels. All these gun are comparable in quality. The only difference is features, price and build quality.

How exactly does chrome aid in reliability

I have a RRA and it has been a great rifle...but I honestly do not think I would/will buy another one

Or a DPMS

Both of them cut too many corners in MFG

But in the end...it depends on what you want....

Most of the tier 3 mfgs cater to the crowd that doesn't run their guns that hard

So, in your opinion, who makes the best AR for heavy use?

How exactly does chrome aid in reliability

In a few ways. First of all, it's resistance to corrosion and pitting helps to retain reliability of the weapon. Many experts claim that along with a few other factors (like the powder and lack of cleaning kits), failure to chrome line the barrels was one of the biggest issues with reliability in the early Vietnam era.

Secondly, chrome is more "slick" than regular steel. The 5.56 cartridge is not tapered much, so much of the case makes contact with the chamber during feeding and extraction.

This is one of the reasons that chrome lined barrels handle steel cased ammo with greater ease than non chromed barrels.

COLT, LMT, Daniel Defense

COLT, LMT, Daniel Defense

When did Daniel Defense start making AR15's on the same scale as LMT or Colt?

 

[hags]

Colt 6921, LMT, Stag....
how's the saying go, you can buy quality once or pay for it over and over again.
I dunno but you get the idea.

 

[hags]

When did Daniel Defense start making AR15's on the same scale as LMT or Colt?

When did they start making ARs at all?

 

[Onmilo]

I voted DPMS for someone wanting a starter rifle.
I don't buy complete rifles, I prefer to build them to customer specifications from a myraid of vendor parts.

Every manufacturer uses some really excellent parts and some really mediocre cost cutter parts.
Weed out the bad and use the good.

Except for Colt and LMT. Top notch bar none.

 

[RockyMtnTactical]

They did a VERY limited run of lowers, and they do some uppers, but other than that and accessories like rails and sling mounts, etc.... they don't. At least last I checked...

 

[hags]

Seriously, of the two "manufacturers" mentioned I know firsthand that one is simply an assembler. They don't manufacture anything. Alot if not most AR "manufacturers" in fact don't, they are simply assemblers or final machinists.

Except for Colt and LMT.

I have heard (from multiple, reputable sources) that Colt is just a name anymore. That their product is not really any "better" or differentiated than the RRA's of DPMS's. Why do you believe that the Colts are worth the extra $$$? Do the RRA's contain any sub-par components? If so, please share the specifics.

 

[RockyMtnTactical]

Who are these reputed sources you speak of??

That isn't true. Colt, LMT and others take more precautionary measures to ensure that the weapon is more reliable.

In a way, when you spend more on something like that, you're buying insurance. Yes, every manufacturer can put out a lemon and every manufacturer can put out reliable weapons. But the higher end companies like Colt, LMT, S&W, Stag Arms, BCM, Sabre, CMMG, etc... make better, more reliable weapons than RRA, Bushmaster, Oly, DPMS, etc...

Lots of guys have reliable DPMS rifles. I've seen Olympic AR15's outrun Colts, but those are the exceptions.

I do think that some people make too much of it. It really depends on what you want your rifle for, and some of the precautionary measures taken by some are overkill.

1. Your sources are wrong!

2. You must be kidding, a 4150, MP tested, pressure tested, stress relieved machine gun barrel or 4140 pot metal garbage?

3. Your sources are wrong!

The lower tier mfg's cut corners

Things like dremeling in feed ramps, not properly staking carrier keys, substandard extractor springs and inserts, incorrect chambers

And no, they do not have nearly the same QC as those that adhere to the mil-spec

Ask any of the major trainers....the guys that see lots of different weapons all on fairly high round count days

They get plenty of students with a bushmaster, RRa, Oly, DPMS that has worked fine for a few hundred rounds here or there

But they fall apart when they get run hard

RMT- I don't fire full auto, I maintain my weapons and Colorado is not a jungle environment.....but thanks for the advice from the vietnam era....

So while I like my chrome lined barrel....I do not pretend that it makes my carbine any more reliable

 

[birdv]

RRA unless your get the match DPMS upper and lower

 

[JonB]

but thanks for the advice from the vietnam era....

too funny

 

[benEzra]

dscottw88 - talked with a dealer at a local gun show for Rock River Arms and he claimed that none of their guns come chrome-lined.

RRA offers the option of chrome lined, stainless, or neither on all their rifles. Chrome lining is $40 more than unlined, according to their website.

Uh, you don't have to pretend, it does. The hard chrome does aid in extraction, that alone makes it more reliable than a non-chrome lined chamber.

It certainly and without a doubt makes it more durable.

Three letters for you and you will be happy , They are RRA

These are guys who bought RRAs and DPMSs and now wish they had bought a Colt or LMT product.
