Are the Ruger uppers Mil-Spec? How is the quality. I was offered one in a trade and don't know much about them. TIA

No they aren't milspec but that doesn't make it bad, they are pretty nice for the money. The only down side I can think of is that the delta ring on these is plastic and doesn't use a spring.

I don't believe the handguards have heat shields, thats the only negative I can think of.



The barrel is 1/8 twist and is nitrided which is pretty nice. The gas block also had a built in QD Mount.





The Mini 14 flash hider also seems like an interesting take.



It's an AR so you can fix a lot of things yourself, but if needed Ruger's support/warranty is amazing and I can't complain. It's a keeper/shooter for sure.

I have several friends who have Ruger Ars with no complaints.

I do not own one, but have heard that the warranty (which is very good) is void if you use any aftermarket parts, even if it's not associated with the malfunction. Of course the work around is to keep all factory original parts and reinstall them before returning if you ever needed service. But I have no first hand knowledge of this.

I had a Patrol 556 I got in a deal, it seemed nice but I traded it.

I had a Ruger AR BM450, very nice quality. Sold to get out of that caliber.
