I just came across your post while I was browsing and wanted to share my 2 cents worth. Nobody who replied here seems to be an owner of the M96 unless I am mistaken.
The rifle is definitely expensive, and a bit heavier than the AR. I have an M96 Rifle that I put over 1000 rnds through prior to converting it into a Recon variant (short barreled carbine). I've since put around 200 rounds through the Recon. The rifles have stainless barrels, the Recons are Chrome lined.
In my opinion, the M96 was worth every cent. It has a very smooth (although a bit long) 2 stage trigger that has an almost gunsmith modified feel (very good). The build of the firearm is very nice. A few early models had the barrels launch during shooting due to a faulty retaining pin/spring design which was corrected long ago. It is quite easy to affirm that the barrel is properly seated, and one just needs to take care to assemble it properly after removal.
Firearm stripping is simple and requires no tools. Recoil is light and the gas system is adjustable to 6 positions from full close to wide open. I use thermolds and Colt 20 rounders most of the time, and the only malfunction I have ever experienced was a failure to eject after switching from surplus ammo to Cor Bon frangible rounds without closing the gas port down a notch (the load simply wouldnt cycle the action without adjusting the gas setting). The rifle has excellent accuracy considering the quick change nature of it's barrel. I've shot at 200 yards and it is easy to group 10 rounds in the vital chest cavity of a man sized target. Average 100 yard 3 shot groups from a rest are 1.25MOA.
This rifle has many naysayers, as well as many who seem to feel that customer service is lacking. I personally would not trade my M96 for any other .223 available. I enjoy shooting it more than any other rifle I have ever owned or shot. I have a Daewoo which is a fine rifle, but it compares to the M96 like an Ak47 compares to an AR15. The Daewoo's trigger can't hold a candle to the M96. As far as customer service, I ordered some spare parts and a factory scope base recently. The sales rep was fabulous and helpful, and the order arrived to Ohio from Utah in less than 5 days. Robinson Armament is a small company, and they have limited resources, so don't expect fast development on new products. Good things come to those who wait.
If you've got money to spend, I would buy an M96 in a heartbeat. If you don't like it you can sell it. I considered the two AR rifles verse one M96 rifle issue when I started looking for a .223, but I don't regret my choice one bit. I have had the opportunity to fire a multitude of AR-15 rifles, including custom jobs with stoned triggers and all the goodies, and I still don't feel that I could have made a better choice than gettng my M96. The only thing that made it better was the shorter barrel Recon kit I installed. I would definitely go Recon if you purchase one, it is much handier and balances much better when shouldered.
Hope my opinion has given you some insight into the highly underrated M96 rifle.
