    I'm new to the pistol ar build so excuse my ignorance when I ask what does a "colt pattern" mean? I know for .223/5.56 builds everything is pretty much interchangeable. I have a cmmg dedicated 9mm lower...,will the tros work on that? And the 3 lug barrel....is that better than just a threaded barrel?

    Thanks for that data! I'm trying to decide between a 5 or 7 inch barrel. Add a suppressor on the 7 inch and it really isn't that short anymore!

    Your Cmmg lower would be Colt pattern. There's a couple more out there like Olympic and the glock mag lowers, maybe some others aswell but most just run the colt style. The tros barrel will work , Go 5" and tros or threaded it would be personal preference I'd say.

    What Dustin said. You can get Colt style anywhere. The Glock style, albeit is neat, is "special". If there is any weird part for it, say a bolt for example, will you be able to replace it in 5 years if something breaks? 10? 20?

    My barrel is a RRA. They call it a 10.5", but they must be comparing it to a 5.56 barrel/bolt. From the bolt face it is actually 11.2", or somewhere there about. I am supremely happy with it. Although I bought 4 magazines from Spikes (Metalform) that were great, but a gazillion $ each, I have 20 or so Uzi mags that I modified that work just as well (but no BHO). I want to say they were $5.20 each at the time. Good luck finding that deal now.

    Accessorized my 5" today. Hopefully with eForms the Wraith XL will be out of jail in 3 months or so.

    Finally have mine in hand. Like the 16", but I'm already thinking about a 8 or 9 inch and a can that will fit inside the handguard.
