Another question....why is colt considered on par with DD, BCM, etc.? I don't see anything about them being better than anything else? I don't believe their QC is all that great after seeing this debacle with the new Python. And the furniture doesn't scream amazing. The materials are what everyone else even decent is using. I see a rollmark and higher-than-worth-it pricing.

That and with with BCM...they oversize their gas ports to be "more" reliable, when other manufacturers aren't and still staying reliable. How does a harsher firing rifle make it a better rifle? (NOT stating BCM isn't good, I like their stuff)

It seems to me...that because the .Mil uses these particular brands, that they're somehow "better" even though our military usually isn't buying the highest prices, most gucci option. They buy something reliable, that is at a certain cost per the decisions of stars and bars. This, to me, reaffirms you don't need a really expensive aluminum rifle to have a good...reliable...aluminum rifle. And that a manufacturer using the standard materials and specs, can make something just as good for a decent price. But what do i know.

they are, or were the main contracted supplier for the us military for most AR15 based weapon systems. .. they are the standard that all the other companies have had to improve upon.
they suck at aesthetics, but as far as quality where it matters: barrels, BCGs, Recievers... second to none.
 
My AR15 is a DPMS ORACLE. About as cheap as you can buy. It has never failed me and its run nuthin but the cheapest ammo. Now, that being said, I don't give a ding dong about sub MOA. For me, if I can ring my 10" steel, I'm happy. Its worked out to 300 yrds, the most I've tried.

Awhile back I bought a POF REVOLUTION for my big bore desires. She's good :)

Personally, I wouldn't hesitate on either end. IMHO, its hard to find a modern firearm that isn't worth owning, no matter the price.

YMMV :D

Are you sure you're not thinking of DD or PSA? I have never come across an overgassed BCM. As mentioned above Colt the "yard stick", the benchmark if you will, they use a gas port size .062" on both 14.5" and 16" carbine length gas systems, BCM is famous for there mid-length gas systems (of which there is no standard) with a .076" port size and that's just about perfect for a mid-length system. DD was famous for having Jenna Jameson syndrome before they dialed it down and my PSA upper is way harsher the my BCMs. One thing BCM does do is use lighter weight buffers for the reason you mention, like the A5 kit comes with an A5H0 compared to Vltor A5H2 in their kit.
 
Won't any part wear out with use?
And isn't that the rub? How much will you use it? How much are you gunna spend to have something that will last longer than 20K rnds?
Guess that I don't use it that much as no problems yet.

Wearing out thru use is one thing, eroding and falling apart is another. Aluminum is unsuited for the heat and pressure generated at the gas port.

drtwt but that's a lotta hubub to say "frankenrifle".
lol
I like to keep stuff simple so just buy Colt.

I'm sure "drtwt" means something but I haven't a clue what so I may be lost in context but that has nothing to do with a "frankenrifle", it is a well spec'ed BCG which is on par with Colt. And yes Colt is hitting the easy button. The AR simply would not be where it is today without Colt.
 
Let me stop y'all right there about Colt and "mil-spec":rolleyes::rolleyes::rolleyes:
Isn't it common knowledge that the Military buys things at "lowest bidder" contracts?

Mil spec simply means the bare minimum specification to meet; in terms of fit, function, and component interchange.

Then why aren't they armed up with PSA? ;)

"Mil-spec" is probably the most abused and misused term regarding AR's.

"Didn't Read The Whole Thread" ;)

Thanks, I should have known.

Probably because PSA doesn't meet the Military Specifications and the contract requirements such as having specific lower parts kits and lowers to go for the actual M4 and M16A4 series ? :rolleyes:

They maybe don't have the specific FFL Class Manufacturer license required for post 1986 Machine Guns (something that Colt and FN Herstal and H&K all seem to hold currently)

Yea, I might have mistaken that info. I read a lot, so occasionally I mix some things up.
Who even makes aluminum gas blocks? I just want to make sure I avoid them.
