survivalshop Posted September 11, 2014 Report Share Posted September 11, 2014 I started looking into who makes the raw forgings for AR's & i'm posting some sights for reference . You may be surprised that your beloved brand , may have not made the receivers on it . Not a big deal though , its who machines & QC , not to mention the parts that go into them & who assembles them. Some Forum posts are a couple years old , so may not be the way it is now , but its just for reference . http://m14forum.com/m16-ar15/114939-cerro-forge-colt-there-s-some-relationship.html http://www.calguns.net/calgunforum/showthread.php?t=50947 Quote Link to comment Share on other sites More sharing options...
shibiwan Posted September 11, 2014 Report Share Posted September 11, 2014 Our forged lower blanks come from Cerro. There are only like 4-5 forge companies out there that makes lowers. Quote Link to comment Share on other sites More sharing options...

Sisco Posted September 13, 2014 Report Share Posted September 13, 2014 Oly is one of the few that manufactures its own uppers and lowers I believe. According to the Gun Digest book of the AR15. Quote Link to comment Share on other sites More sharing options...

survivalshop Posted September 15, 2014 Author Report Share Posted September 15, 2014 These are AR 15 Receivers . All the Tactical Machining Uppers I have, have the " square " marking , The Tactical Machining 300 BLK , lower has the " Key " marking on it , The POF NIB upper has no markings ,but POF USA on it , The two Olympic Arms A2 uppers , one is from the late seventy's , it has no markings , the one from the early eighties has the " EK " by the rear sight, The Olympic arms, pre ban Lower has no markings I can see. I took more photos , I have to break out the two Tactical Machining Lowers I just picked up there a month or so ago & see what markings they have .

98Z5V Posted September 15, 2014 Report Share Posted September 15, 2014 Olympic does forge their own stuff. Alot of people talk $hit about Olympic Arms, but there aren't any other companies out there forging their own uppers and lowers, and cutting their own barrels. Oly barrels are some of the most accurate out there, but people blow them off, based in "internet legend." Oly barrels are fucking accurate as all hell.

98Z5V Posted September 15, 2014 Report Share Posted September 15, 2014 Olympic does forge their own stuff. but there aren't any other companies out there forging their own uppers and lowers, and cutting their own barrels. Just wanted to highlight that, in case people didn't know that info. Olympic Arms forges their own uppers and lowers, and the produce their own barrels, from raw materials. They cut their own rifling. No other company can say that they completely make their own rifles in-house, besides Olympic Arms. Let's see some challenges, there are none out there. Daniel Defense doesn't forge their own uppers and lowers, so let's cut the $hit-talk to a stop right there on them. No other company does this. None. Oly is the only one.

Robocop1051 Posted September 15, 2014 Report Share Posted September 15, 2014 Not even Colt??? Who makes Colts barrels? Quote Link to comment Share on other sites More sharing options...
planeflyer21 Posted September 15, 2014 Report Share Posted September 15, 2014 What about Remington? Quote Link to comment Share on other sites More sharing options...
shibiwan Posted September 15, 2014 Report Share Posted September 15, 2014 What about Remington? Same as DPMS, usually Cerro Forge or Anchor Harvey. Their 308 uppers are made out of custom extrusions and 308 lowers are billet (except the new G2, which looks like a forging) Quote Link to comment Share on other sites More sharing options...
planeflyer21 Posted September 15, 2014 Report Share Posted September 15, 2014 Certainly Remington didn't get the M4 contract with billet lowers? <dontknow> Quote Link to comment Share on other sites More sharing options...
98Z5V Posted September 16, 2014 Report Share Posted September 16, 2014 Not even Colt??? Who makes Colts barrels? Colt doesn't forge their own uppers and lowers, brother. Not saying Oly is better than Colt - no way in hell. Just saying they produce their own stuff. Not saying Oly is better than DD, either - no way! Oly is just an in-house operation.

washguy Posted September 17, 2014 Report Share Posted September 17, 2014 Oly lowers were plentiful back in the 90's.....if you built....that was a go to :) Wash Quote Link to comment Share on other sites More sharing options...
survivalshop Posted September 22, 2014 Author Report Share Posted September 22, 2014 90's ?, Olympic Arms was the only company that sold AR build parts in the late 70's . I have one I built in the late 70's with there parts & there ,S/S ,NM 24" HB , 1-10 twist barrel . Still shooting great , the only thing I didn't use of there's was the BCG , they only sold AR 15 BC 's & I use only M16 BCG's . Back then you couldn't get M16 BC's unless you were a Class Three Dealer . This rifle had the original A2 upper receiver & A2 front sight up until last year when I put a TM flat top on her & a Burris TAC 30 3x9x40 scope & rifle shoots 2" groups @ 200 yards . I can not even say how many rounds have been shot out of that barrel. This rifle also has the first FF hand guard on it from back in the late 70's . They were ahead of the game as far as parts for building AR's . Quote Link to comment Share on other sites More sharing options...
blue109 Posted September 22, 2014 Report Share Posted September 22, 2014 I had a old "billet" lower from the 70s made by advanced armament inc. 3 digit serial number it looked like a block of aluminum hacked into shape with a machete lol. kinda wish I still had it just to hang on the wall.
