AR 15 Lowers?

[Cold Bore]

Like in all things, you get what you pay for. Looks is one thing, but accuracy is another. Mixing parts is not something that leads to the best accuracy and smooth functioning, especially in an AR. And the degree of accuracy depends on the person buying the rifle and how much they are willing to pay. If you looking to get away with a shooting AR Rifle that puts together 1.5" -2" groups at 100yds, go buy a completed rifle at your local sporting goods store for less than $1000. But if you are looking for an AR Rifle for serious accuracy, look to spend 2X+ more for glass.

Gotta disagree here.

"Mixing parts"? Funny, guys do it all the time with benchrest bolt guns, looking to achieve the utmost accuracy, and it's a good thing. But do it with an AR rifle, and now it's bad for accuracy and functioning?

Spend $2000 on one for "serious accuracy"? No need.

It is not hard to build an accurate AR-15, affordably.

And of all of the components, the lower ranks well below other parts when it comes to both accuracy and function/dependability.

I think any lower will work just fine. Brownells had bushmasters on sell for $49 a couple of years ago. I compared one of them to a Spikes tactical and another brand that I don't remember the name and they were all the same.

At one point a few yrs back 90% of AR lowers, no matter the markings on the sides, were made by one of about 7 manufacturers. These days there are some new machines out there milling them out, but all in all there aren't nearly as many companies cutting aluminum as there are selling it.

They were:

LMT = LMT, Lauer(old), DS Arms, PWA, Eagle, Knights Armament, Barrett, Bushmaster (?)
CMT = Stag, RRA, High Standard, Noveske (old), Century , Global Tactical, CLE, S&W, MGI, Wilson Tactical, (some?) Colt, Ratworx
LAR = Grizzly, Bushmaster (L Prefix), Ameetech, (?)DPMS, CMMG, Double Star, Fulton, Spike's Tactical, Noveske
MMS = Mega, Gunsmoke, Dalphon, POF (forged), Alexander Arms, Stinger, Spike's Tactical(old)
JVP = Double Star, LRB
Olympic = Olypmic, SGW, Tromix, Palmetto, Dalphon, Frankford, (old) Century
Superior = Superior Arms, Lauer, Grenadier Precision
