I'll check them out when I'm ready to buy my next rifle, regardless of what it is. I'm a little late to the AR game... got a D**S P****r last year and it was unremarkable enough that I punted it and said I'd just defer that project until after I'm a bit more well-read.
I needed a solid, accurate scoped bolt action in .308 for longer range work where the 16 AR wasnt the appropriate tool for the job. Cabelas had the package at less than $400.
The Nikon BDC was mounted at the factory. I couldnt pass it up. Its the Model 110 with the Accu-Trigger. Best out of the box trigger Ive ever seen. With 168 grain Sierra Match Kings 400 yard shots arent a big deal.
A trained 2 person team could raise a real ruckus with it if they had a mind to.
If you want to build a nice AR I can highly recommend RGuns in Carpentersville IL.
They put together a real fine M4gery for Mrs. L. Prices are quite reasonable considering the quality. For the record I have no affiliation with them other than a very satisfied customer.
Best of luck to you.
