While I recently spent a lot of time and money upgrading my multi-gun competition rifle to a high standard, I didn’t forget about my competition PCC. Whenever I go out and shoot Steel Challenge, I like to do the “two guns” thing and shoot both a PCC and a pistol. I figure most of my investment is time, and I may as well shoot as much as possible while I’m at the match.

The experience with my competition PCC hasn’t been smooth. In fact, I’d probably say it has been the most finicky ARs I’ve ever built. I spent a lot of time just getting my basic functionality working, and then I later had a very unfortunate catastrophic failure when a bullet got stuck in the rifling during manual extraction. But I persevered through those problems, and wound up with a reliable, accurate PCC. Now I’m on the next step: increasing performance.

When Taccom announced their Delayed Blowback Recoil System (DBRS) a couple years ago, I was intrigued, and to be honest, a little skeptical. Using magnets to delay bolt movement sounded hard to believe. But I saw some positive reviews of it, and decided to give it a try, in conjunction with Taccom’s Extreme Short Stroke Bolt (ESSB).
