Questar ar15

I have one.....no issues whatsoever.
I already have a pimped out 7.5" shorty AR. I wanted a 'beater' AR but refuse to buy chinese. My buddy bought an M4gery around the same time and wished he bought one of these when he realized he couldn't take it over the border to the US....
I've been running mine with the new Lucid optic.
Keep in mind that the Vulcan lower is partially polymer.
I haven't been able to figure out who makes the upper though.

Most people will criticize the polymer lower. Even though the newer rifles are pretty much using as much polymer as possible including lowers such as in the ACR. There have been reports of the Vulcan AR lowers cracking. I don't know if this is a product quality issue or a matter of trying to use polymer for a design not meant to use polymer.
The problem is in resale and pride of ownership. The aluminum lowers when done properly look great and complete the solid well made look of the rifle. The resale would reflect this. If you ever decided to replace it you'd be at the same price as a Stag or Armalite complete rifle. The Core15 is another cheaper alternative that actually looked pretty good when I saw it. The NEA isn't really out yet and I haven't seen one but it appears to be an excellent buy for a non collecting AR rifle.
Just from looking at the picture of the Questar rifle my gut instict says it might be a Rock River Arms upper? I could be wrong but that was my first guess when I saw it.

Where is the thread? Is it 5 years old? Post the link.
One picture means nothing.
The upper is american made.
Just found it on a google search, post could very well be old.
I understand the upper is american made I was curious what the manufacturer might be.
I found the post pertaining to the RRA lower for $100 extra.
Hey, I've got 1 too, and the only issue I found was with Vulcan lower was that you can't install a Magpul MOE Trigger guard with out filing it down (quite a bit too), since there seems to be a structural cross ridge on the receiver where it would normally be empty on an aluminium/steel lower. That said, I've replaced mine with a Spike's tactical for 149$ I believe, and it feels more solid. Also, I found that the mags weren't dropping free as smoothly.
I'm also in the process of trying to acquire a Danial Defense rail set to replace the stock handguards, but they seem to be out of stock everywhere.
Interms of shooting, it shoots really well, I just wish they included a front-sight post tool to adjust your sights, I found it was kinda a pain to adjust them with just the bullet tip.
I'm pretty sure the gas system's carbine length, also I believe the stock's a commercial stock, and not milspec.

I just ordered the Questar AR15 and added the rock river arms lower receiver for $100 extra.
All in all I got the rifle, with the RRA arms lower and two LAR15 magazines, taxes and shipping came to $1,200 total pretty good deal.
I'll let you guys know how it shoots once I pick an optic up for it I'm thinking about the lucid HD7.

From a materials engineering standpoint the carbon aramid is much harder and stronger than aluminum but not as tough. The rockwell hrc is very high for hardness which means very good wear resistance but also the young's modulus is high which means the material will not have much give before it breaks. Think titanium. Much stronger than steel per weight but more brittle. Aluminum is very ductile which makes it very tough but the tensile strength is much lower. Toughness is the ability to take and absorb impact.
So basically the vulcan is much stronger and harder just dont drop it or hit it with something too hard. For myself I wouldnt hesitate to buy it but I would just keep that in the back of my mind. I would be happy to have the extra wear resistance and under normal use it is much better. If you think you might use it as a hammer or beat on it with a hammer then get an aluminum lower.
