Not sure those two rifles are similar (the DPMS Recon G2 versus the DPMS MOE G2), the barrels appear to be different which sways the vote for the Recon (SS barrel), but I'm not familiar enough with these rifles to know more.
I'd definitely wait for the Recon G2, but hopefully NTM or Epoxy7 can chime in with their vast amounts of AR-10 knowledge to clear this up.
Cheers D
When it comes to the G2 I definitely take a second seat to NTM! In fact I only bought one after he mentioned them. He was the pioneer with going to that platform and I frankly coat tailed that one!

I would wait for the Recon. The price difference of $1630 vs $2000 is more than offset with the trigger and the barrel. I prefer the SS thicker barrel over the pencil barrel of the AP4/moe model. The G2 needs it's own barrel. You can't drop in a G1 DPMS or AR10 barrel with these. So trying to change it around is a pain. Plus the AP4/Moe models still have the triangle front sight which means removing it and adding a low profile gas block if you want to bring your G2 into line with current carbines. The trigger is very good in mine. It's a two stage that is about 4.5 pounds. I've felt no need to change it out for a higher grade trigger. To improve on the trigger you would have to go Giselle so factor in another $300 plus dollars for that. Plus in the case of the G2, it's new so finding out the hard way that certain parts may or may not work won't be fun. Get as close as possible to the finished product. You'll save time and money.
I ran into an example of this with my G2. I replaced the commercial carbine stock (Thanks Cerberus groups for reminding me this was a DPMS product!). I put on a PWS enhanced buffer tube. Went on great. Looks awesome and adds single point slings. But....... I have run into a problem. Something doesn't play well and I have run into the bolt not going back far enough for lock back. So back to the stock carbine buffer tube. The PWS has a slightly narrower interior which I think might be an issue causing binding with the buffer spring. It's not a huge deal for me as I have other carbines I can use this on and the stock I'm trying is a FAB GL-shock so it can work just fine on a commercial buffer tube. But it is something to consider.
As NTM has mentioned, the front handguard is crap. Get rid of that and add the MI G2 keymod. You just lost half a pound of front weight. With the stock rail the gun is nose heavy. Lose that half a pound up front and it should balance it out nicely. I'm still waiting for my MI handguard. There was a mix up back ages ago when I ordered mine. I just reordered mine again a month ago. MI was very quick to jump on this platform.
The heart of the G2 and basic components are it's strength. The barrel, AAC flash hider, 7075 forged upper/lower, bolt, trigger etc are all very good. The handguard, meh. The buffer tube and stock are also mediocre. But those are easily changed around without costing too much. The magpul moe pistol grip isn't bad at all. But I preferred the Ergo gen1 so I went that route.
When I compare the G2 to other AR308 rifles, I'm comparing it to my DND AR10, SASS AR10, DPMS G1 LR-308, LMT mws and a newly acquired KAC SR25 ECR 20". So I don't say this lightly when I state like NTM that the G2 is something special. Especially as a 16" carbine.. The LMT mws is heavy but as a 16" carbine I would be able to field one. A 16" SR25 with dimpled barrel etc would be even better. But.... both of those platforms are very expensive and the G2 solves the weight and form issue at the heart of the platform rather than with carefully chosen accessories. The G2 solution goes to the heart of the issue rather than just trying to cure the symptoms. It's also significantly less expensive in comparison.
When you look at the BCG for all of these platforms, the G2 is the current winner. I used to actually prefer the AR10 one to my LMT (pretty much identical bolt to the SR25). The AR10 bolt looked like a big AR15 bolt and frankly just seemed more military grade. The LMT/SR25 bolt looked more high end DPMS G1. With the G1 bolt being my least favourite of the bunch. It just screamed commercial grade. The LMT/SR25 bolt was acceptable and works very well. But.... I really preferred the AR10 bolt/BCG. The G2 however now walks away from all of these in terms of the best BCG design. It has everything I liked about the AR10 bolt along with dual ejectors, a one piece no screws/staking required gas key (new ADCOR 556 also has this) and it looks like a military grade AR15 BCG.
The bolt in the middle is the G2. Top is AR10, bottom is 223 AR15.
LMT MWS BCG (ignore the fancy coatings, and just compare the architecture)
The BCG is actually a big deal with the G2 for both the reasons I've already mentioned but also weight and recoil. you're losing about 1/2 pound of mass with the G2 BCG. Also the diameter is AR15 although it is a bit longer. It's significantly smaller and lighter than the current AR308 BCG. Which allows for that AR15 form factor in both the lower and upper.
Of course the biggest advantage with this is as a carbine. It really doesn't matter for DM or tactical target rifles. For AR308 rifles I tend to lean towards the 20" SS barrels. I'm actually very glad I have gone this route, as the G2 makes all other 16" AR308 carbines obsolete. When I finally picked up a SR25 it was a no brainer to go with the 20" simply because the G2 fills the 16" role so well. I even traded my RFB which until buying the G2 was something I would have never considered simply due to the super short form factor. I just hope I don't get burned on that one come election time.
