Would like some opinions.

I've been wanting an ar in 6.5 Grendel for a while and want it to be more of a target rifle, as opposed to a combat rifle. I've already decided on getting this package deal from Odin Works for a barrel, bcg, bolt, handgaurd and a some other little parts.

Question: is there really and perceivable accuracy gain from a higher end/more expensive reciever set versus something like a cheap Anderson set?

No it's all about a good barrel with bolt and a good trigger the remainder just needs to be functional

Yep, but if I was putting several hundreds of dollars In the barrel, trigger, and BCG id spend a few more dollars and get a nice set of upper lowers. You can get a nice set of billets from joeboboutfitters their Spartan line, or Runner Runner Guns in McKinney they have the same upper/lowers as JBO but have Texas themed ones or I believe recoil gun works have the same. They're only about $120 for the lower and $120ish for upper, I'd much rather have a set of them on a precision build than the Anderson $45 lower. Just me though I'm sure the Anderson would work fine.

A matched receiver set seems like it would remove one more variable. I don't like the slop in my Frankenstein ARs and the play seems like it would effect accuracy.

As mentioned above, accuracy will be based from barrel, bolt, and trigger. But like Kroyal said, if you're gonna spend $ on a nice build you might as well make it nice.

Why 6.5 grendel over 6.5 creedmoor?

6.5 creed would be a totally different beast, Ar-15 (Grendel) vs Ar-10 (creed) more $ involved for an AR-10 build

For a target Ar-15 I'd spend on the barrel, trigger and ammo (handloads). any mil-spec 15 lower/upper should suffice

Truing/bedding upper receiver with barrel will also squeeze every bit of accuracy out of your build. I've heard of folks using blue loctite to bed barrel extension with upper receiver. DONT use retaining compound if you ever plan to swap barrels, you'd need to use heat to release bond between upper receiver and barrel extension.

Might seem that way but it doesn't. I have two 450.00 fancy matching receivers and one has slop and the other does not so just because you buy high end you may still have to make minor adjustments to remove play.

Most all of the "high end" machined lowers have a tension screw under the grip. You might look and see if yours has one.

Most forged lowers have that nylon screw (really the only reason to get one)

Did you mean billet? I've never seen a forged lower with a tension screw.

Billet has the nylon screw, I haven't seen a forged lower with them yet. High end or low end receivers doesn't matter. As long as your upper and lower receiver mate together well with minimal to no play you're good to go. Aside from barrel and trigger setup.

If I was building a high end precision rifle I'd probably do that wilson combat matched receiver set. Looks very nice.

I like noveske barrels a lot but there are plenty of other good ones. The average shooter won't be able to tell the difference in most of the higher quality stuff.

If you want forged, Seekins makes a good set that is made to have no slop. I built my last SBR off that and it's excellent.

I don't like sloppy receivers because it's a distraction when I'm shooting. Doesn't affect accuracy though inherently but distractions do.

Accu-Wedge is a cheap and effective way to eliminate slop.

yes

Very cheap and great way to take up any slop.

Aero Precision Gen2 forged lowers have a nylon tipped tension screw to reduce play between upper and lower. They are the same price as most normal forged lowers.

Actually, an o-ring on the front lug is an even cheaper way to eliminate slop. Can't remember the size.

I went through this same process about a year ago and spoke to several companies that build them and the common trend was a preference for the precision machining and how tight the barrel fit into the upper receiver. Wilson was mentioned as top notch as was Mega and Spikes. I went with the forged Mega as it does have the nylon tipped screw to eliminate movement between upper and lower receivers. I also built a Seekins billet and mated a 20" ARP barrel on it and have been very please with .5 to .7 5 shot groups.

Nope. I'd buy a Krieger or White Oak barrel and a good trigger.

Interesting, I haven't purchased an Aero lower in a while. My last one, now an SBR, was their ghost lower.

That's what I did.

I had to look up the Accu-Wedge price. I guess the actual Accu-Wedge brand one is not cheap. I bought like a dozen of the cheaper version.
