    Is receiver flex really that much of an issue? Is there any quantifiable evidence that shows how much accuracy is changed with different receivers? Also is the tighter fit of BCM receivers beneficial to accuracy by any quantifiable amount? When I look at products that say this is better than x product, numbers and testing is what I want to see.

    Wonder if these will be standard across the lineup and wondering if a price increase will happen.

    Hoping these will be a selling point over the competition instead of price increase type of item.

    Using the search feature and reading past information regarding the MUR, some of your questions will be answered.

    My upper blew up a few years back. It was a MUR and I was using an LMT E-Carrier. IMO the damage was limited due to those two factors. Most of the MUR damage came from prying the upper open to get it disassembled.

    If you check out the work from a few years back of Kino Davis, you will find a lot of info on flex testing and the results. IIRC, there were some companies who really freaked out when they saw the results and made threats, and got him banned from another board. Its been a few years, so please forgive me if the facts are slightly different, but that should be the gist of it.

    Do we even know when these will be available? I need a upper for a Barrel and my URX and my local shop has BCM uppers in stock. I just wanted to know if this will be available to order or use because like always lately I am not waiting...

    I have heard nothing about even rough ETAs with this project. Not that I claim to be all knowing by an stretch, but I figure it gives you a little info instead of no info.

    If it makes you feel any better, UPS just dropped off a 9mm, 3 5.56, 1 300BLK, and 2 308 barrels. I don't figure any of them will be wearing the BCM upper in their first evolution.
