By Jeff Gurwitch It’s been 8 years since my last Competition to Combat article, written back in 2018. It was the last year of use for both the Daniel Defense 10.3 CQBR upper and the 14.5 RISII non-front sight post upper. Beginning in 2019, U.S. Special Forces started to switch over to the Giessele URGI upper with mid-length gas system …

By Jeff Gurwitch July 20, 2021 Back with yet another review of a Tyrant Designs product, this time their Glock Magwell(s). I’ve been running one on both a Gen-3 Glock 17 and a Gen-5 Glock 19 (G19) for about three months now, and am very satisfied with the results so far.

During this time, it’s stayed continuously loaded (except of course when being used at the range), and has been …

Thanks to photos and feedback sent from previous team members of their rifle setups, they’re currently employing overseas as of Fall 2018, I have …

By Jeff Gurwitch June 4, 2018 I first came across the M855A1 Enhanced Performance Round (EPR) during my first deployment to Afghanistan back in 2012. At the time, M855A1 was only being issued in war zones, so none of us had any experience training with it prior to the deployment. While the penetration capability of M855A1 was pretty well documented …

By Jeff Gurwitch April 22, 2018 M855A1 ammunition has been in use overseas since at least 2011, and has been in widespread service at most U.S. Army bases since 2014. I myself first saw it in 2012 in Afghanistan. Now, when M855A1 first came out, like many others, I heard the stories that due to the increased pressure the round …
