Again, someone making there own because a company may been doing other things has nothing to do with the announcement of this firearm. I would suspect it has more to do with ones ego.

Wrote them four years sgo about this very item,they sat on their —– so I built my own,sold the AR-556 I owned and while it’s about time for Ruger to get with the program,they can keep my copy as I’m perfectly satisfied with what I built sans the Ruger logo.

What has you building an AR to do with this weapon?

@KJ Hoover, He is just sharing his experience with the company that makes the weapon. I suppose that is not an important factor, if everything goes right. On the other hand, if something goes wrong …


There’s a definite advantage to building your own from scratch… serial number and no registration of any type if you live in one of the majority of states that allow you to do that. Mine has an 8 3/4” threaded barrel and cycles flawlessly.

Ruger sat around,not offering a product that even four years back most of the major AR producers had in their line ups,while Ruger didn’t offer that chambering even in their carbines so they lost out on sales.You snooze you loose.

Should we count the number of new models they came out with in that period? Snooze? That’s funny!
