AR-10 Lowers
« on: October 27, 2016, 11:13:58 AM »
I want to get at least one, maybe two. SR25 pattern. Any recommendations for manufacturers?

Does Joe sell stripped Broadsword lowers?

    Due to the lack of standards in the AR-10, I usually recommend getting the upper and lower from the same manufacturer to be on the safe side.   

    The Alexandria Pro-Fab lowers that AIM sells are pretty good, and low cost.  I got a couple of those.

    I have been very happy with my TN Arms polymer lowers.  They have performed well to date.  I have one complete build and four more in the wings on these lowers.

    If you want aluminum, and I think there are many good reasons not to go polymer, I would look for a deal on an M5 from Aero.  Currently the only thing I know of in stock is a CMT billet set from Red Barn:

    PRetty steep though, at least for me.  It's prices  like this that keep me coming back to TN Arms.  They work, they are light, they have a no questions warranty, and they are under $100.

    I got the APF 20" complete upper from AIM for one.  Got their stripped upper for the other since I will be doing it in 7mm-08.

    I will look through my other sources when I get home to see if anyone else has anything in stock.

    Yeah, I've been poking around and and everything is out of stock everywhere.

    I did an AR-15 build with an Aero lower. My only issue was that the trigger well was a bit narrow at the front, so the POF trigger pack wouldn't fit.

    I am wondering if the manufacturers are focused on AR-15 production.  The magpul AR10 magazines have been a little scarce too.  Especially the 20rd black.  They are still around some places, but they have been on backorder at Brownells for a couple months now.

    Also they post coupon codes on their Facebook. Might see if they have 10% off for Halloween or something.

    I used a Fulton Armory upper on the 358 Winchester build.  For the others I picked up blem LR-308 lowers on gunbroker for $40 each.  They are bare aluminum so I will cerakote them the next time I have that kit out.

    Well, other than the occassional (spendy) billet lowers, the world seems to be almost entirely sold out of .308 AR lowers.

    Still pondering the TN Arms poly-hybrid version.

    You can try http://www.apfarmory.com/lower-parts/

    They cost $100 more than the ones AIM was selling though.

    I ended up ordering one from APF and one from TN Arms.

    I'm digging the look of APF's 'Hunter' upper.  Swap out the birdcage flash hider for a comp, and it's 3-gun time. (Yeah, I know they make a 'competition' upper, but the Hunter is 18" and the competition is 16".  I like 18" better.)

    Glad you found one.   It's too bad you couldn't get it from AIM though, they had them for $100 less than buying direct.   However, AIM does still have the 18" APF uppers for $470.   I was happy with the 20" model I got.

    Alex Pro Firearms and Alexandria Pro Fab are two different companies.  Might explain the price difference.

    Alex Pro Firearms and Alexandria Pro Fab are two different companies.  Might explain the price difference.

    I think they are technically different, but somewhat related.   They are located at addresses right next to each other and the people involved are related.   I think one actually makes a lot of parts for other companies, but for some legal or tax reason they keep them separate.  If you look at the parts, they are the same.  Especially the handguards, they use a proprietary setup that nobody else does. 

    EDIT:
    Here's the bio from the Alex Pro Fireamrs facebook page.  So basically Alexandria Pro Fab is a machining company that does some gun parts in addition to other stuff.   The firearms company is basically their gun distribution business, from what I can gather.   Anyway, the parts were good.  I had no trouble at all putting mine together.  I'm going to order a bipod for it next week then get out to the range. 

    "Alex Pro Firearms was started by the owners of Alexandria Pro Fab, a precision machining company located in Alexandria, Minnesota.

    We have been in business since 1976, where we have been making highly precision components for years. We have always been passionate about guns and making the best quality product on the market. Our products are 100% made in the USA."

    Odd...on the "Contact Us" page at http://www.apfarmory.com/contact-us/ it says:

    We are not affiliated with Alexandria Pro-Fab in any way!

    Just like that, in big red type.

    Yeah that is weird.  Saw some discussion on AR-15.com about it too.   Certainly looks like they are related to me.   Their buildings are right across the parking lot from each other if you look them up on google maps.  Maybe they broke things out into distinct corporate entities when APF was spun off?

    Use these guys here for the .308 takedown pins.  The APF lowers take the longer .308 style pins and regular AR-15 pins won't work.  Their standard set is only $12 and they usually have a 10% off coupon available too. 

    http://ar15xtreme.com/

    You might also consider a bigger magazine release button or mag catch.   The standard AR-15 one will work, but the button doesn't quite stick out as far as it should, the catch is a few threads too short.

    Alex Pro offers a complete .308 LPK.  I figure that'd probably be the best bet.

    Hmmm...one closer look, there are some differences between the two uppers as described.

    Alexandria - nitride BCG, mid-length gas

    Alex Pro - Nickel boron BCG, rifle gas

    Are those differences worth ~$500?  I'm not sure. On strict price accounting, probably not.  How much difference does rifle vs mid-length make in .308?  I know most 3-gunners prefer rifle length in .223, but for normal functional purposes it's pretty much a non-factor if you get the buffer right.

    Either length should be fine.   There have been lots of guys posting build reports on AR-15.com and nobody has had any function problems yet.  The only issues have come from compatibility between these and certain other brands of lowers, most notably the PSA PA-10.   I think PSA based their .308 stuff off the Armalite pattern,  and these are DPMS pattern.    Of course with AR-10s, I think it is best to stick with uppers and lowers from the same place, just to be sure. 

    I think both of these also lack the serrations on the bolt carrier, so the forward assist won't work.  However,  that's not really a huge issue.  I've never had to use the thing on an AR,  and if your gun is so dirty that you need it,  you probably should just clean it.    If you must have it,  you can always buy a different bolt carrier.
