I picked up a few of these uppers. TNW is great when it comes to there belt fed guns. They were having trouble giving me in depth answers regarding the AR uppers. There is a 6.5 grendel barrel available. I am currently working to get a 20" SS barrel and bolt for my project. I was shocked to find mixed reviews online regarding the uppers. I have not been able to find a better quick change upper for the price. You really can't beat it if you are a fan of the piston system. I have fired the 5.56 extensively and never had a problem w/carrier tilt. I like the reduced carbon and heat. As long as you clean and lube occasionally everything runs flawlessly. Anyway, I will be picking up the Grendel barrel/bolt ASAP and enjoying the rest of my summer. I am keeping 1 and hoping to sell the other 2 I have to help fund project. Price for the complete uppers in 5.56 with piston set up and bolt,carrier,etc. is $725.00 ea. These are brand new coyote tan powdercoat w/M4 profile 16" barrel. Barrels and bolts are currently available at TNW in 6.8SPC 7.62x39 6.5 Grendel and a few more. I should have a direct line on them soon. I will post a price for 6.5 bolt/barrel when I can get them in my hands. If you are interested pm I will be happy to talk more about these. I am just a hobbiest, so I won't have these available indefinitely.
