Question for little pew pew builders

Recommended Posts

Hey guys, I would like to build an Ar for my wife in 556 (gasp!), and I am sure that some people build normalish ar's, and I trust the people here more than anywhere else. I want to build her a light weight, and very affordable Ar. But this topic could be valid for 308s also...

I am a 1911 guy. A steel guy. For Ar's, an aluminum guy.

 

But is a "quality" polymer lower acceptable, or foolishness?

Ive also pondered the polly but what can be gained by a few ounces otherwise made me stick to aluminum frames where it goes bang ! But if its not a frequent or abused rifle?? 

Edit: i have had no trouble with anderson lowers! At 40$ thats a plus!

An Anderson upper and lower set will cost about $115-$125. The only polymer set I'd suggest is the KSP (Kaiser Shooting Products, out of AZ), but that'll run you +$200 per set.

LPK w/ ALG ACT Trigger $75

AR15 "Semi Auto" BCG $75

Faxon lightweight 16" (or 14.5") barrel assembly with a simple comp $300

Magpul MOEgrip (she'll love this) $18

MFT Minimalist stock/buffer assembly $100

 

There's an entire build for under $800, and should be pretty dang light. Now that's no where near the lightest.... but that's $$$. Farkle has a polymer and Titanium build that is going to likely be under 5 lbs.

Anyone heard of Tennessee arms Co? These lowers are supposed to be pretty sweet, are cheap, and light. I have heard good things.

The Mag lowers and uppers are really cool, but more spendy.

 

And I think it is battle arms that is making a REALLY cool looking matched light weight upper and lower... That thing is beautiful.

 

I know that I can go forged aluminum cheap. I am thinking of balancing cost, weight, and strength, and looking at everyone's options. :-)

 

I wish I could do this build for 500ish, but I want to get nicer parts, so I'll do it one piece at a time.

Save yourself the headache and potential liability Jacob, the polymer lower is $49 bucks and .38lbs, and this 7075-T6 aluminum lower is $55 and .53lbs... Its a no brainer IMO.

Not often you can get that kind of piece of mind with so little in exchange respectively! ;-)

And the 7075 type is battle proven reliability .

I'll throw in my 2 cents.  My wife doesn't like a lot of recoil.  A heavier rifle has less recoil.  My wife will complain about a rifle that's to heavy or kicks to much.  If I was going to build my wife an AR15 it would have a short lightweight barrel and handguard.  The weight that's farthest from the shooter feels heavier than the weight next to your shoulder.  I wouldn't care so much about the weight of the receiver.  Quality is more important there.  It would definitely be Aluminum.  I'd go with a A1 stock with National Match lead weights. The weights should help with recoil (Yes, my wife thinks 223's have recoil) and balance.  The A1 is better than A2 for her short arms.  I'd also consider a short carbine stock to bring the weight closer to her shoulder. 

 

Of course, my wife prefers 22's and 410's.  Hopefully your wife has graduated up from those already.

Palmetto has full kits minus the lower receiver for $379 on a regular basis and you can pick up an Anderson lower for $40 if you look around. $420 to build an AR-15! I've done it, only mine has a bumpfire stock on it instead of the one that came in the kit.

That is a very good deal for a basic mil-spec AR, bout as cheap as its gonna get for anything worth having, and you can keep it paired as PSA has their stripped lowers on sale for a very aggressive price too regularly, or pick up a PSA blem, you usually can't tell where the blem was...

GG, I didn't have any problems at all with the PSA kit on the Anderson lower. I think the fitment issues are only with their 308 platform. I haven't heard of anyone having issues with their AR-15 stuff.

No no, the mil-spec stuff in an AR-15 build will join up just almost always, occasionally there are very subtle particulars that annoy me when mating receivers from different manufacturers, and most of my earlier guns were that way, but you are right there are no worries there, honestly was more of an anal thing on my part about having a complete gun with matching receivers... LOL...your idea would work without complication I am sure. ;-)

Anderson is not bad, I have built two for my kids that I picked up locally, and they ran perfectly.

I am building an Aero Precision 308AR now, and to be perfectly honest, if I was in your shoes even though they are twice as expensive I would go to them in a heartbeat, very nice quality, price point, and customer service.

Check them out, you might like what you see!

Alright, brother, you're getting a little antsy already - here's a sneakpeek.  Just got it together tonight, so I have no idea what it weighs.  The barrel is the Faxon 16" midlength pencil barrel, the rail is the ALG V1 M-LOK 10" rail.  6.13oz for the rail, including the barrel nut.  PA microdot on a Fortis mount.  The buttstock is temporary, because Mike rushed me and I couldn't get the correct buttstock that's gonna go on it.  I'm gonna shoot it like this on Sunday, and change out the buttstock later.  It's light, overall - damn light.

Mine above is using the Aero Precision forged lower and the X-Products forged upper receiver.  If you look closely at the pic, I lightened the upper receiver a little bit.  I'll do more on it, before I Cerakote the shiit out of it.  That was the upper receiver that originally came with the Can Cannon, but I mounted that thing to a different upper receiver when I got it.

^^^^ Hey Tom, I know you like to Cerekote your weapons so I have a question about that. When the weapon is anodized it increases surface hardness of the aluminum, when you sandblast it and then Cerekote it, does that reduce the surface strength of the metal to any appreciable degree?
