Brownells USA The Device 29/06/2018

I got this when it was new. Before it was at Brownell's. Heard about it locally and had to check it out.There have been some minor modifications since, all for the better, but mine is still going strong. Do you want to lock an upper in and do whatever you want to with it? This is the "Device" for you. Do you want to tweak a scope? flip it over. This thing is made to last, kinda taking us back to when craftsmanship was a thing. The price is up there, but do you want to buy one, or 4 of the same thing? Comes out to be cheaper in the end. I just re-read my post, and it sounds like a plug...well it kind of is. I friggin' love this thing. It does everything it is supposed to do. Put that barrel on with something else, then use this...You will know what I mean.

Brownells USA MK1MOD0 Device 26/08/2017

I have tried a ton of tools and fixtures to install barrels and rails on the M16/M4 platform. This is the best tool I have used to date. Can't wait for the SR25/AR10 version to come out. Price is high but worth it. Way better than the reaction rod. Thank you.
