If you’ve been looking for a Browning Buck Mark rail that mounts under the barrel, Performance Services LLC has got you covered. Known for their bolt-on rail for the Ruger Mark IV 22/45 Lite, they now offer a version specifically designed for the Buck Mark with a bull barrel. And just like its Ruger counterpart, this one installs in minutes and adds serious versatility.
Clean fitting Browning Buck Mark Rail, no permanent mods
The two-piece Buck Mark under-barrel rail is precision machined to clamp securely around the barrel. No drilling, no tapping, just carefully tighten down the two screws while ensuring it’s aligned properly. Fitment on my test pistol was excellent. It hugs the barrel closely and feels solid. It almost looks like a factory part, not like an afterthought. Note that I’m using it on an aftermarket TacSol barrel. The Performance Services LLC website lists all the compatible models this mount currently works with.
Machined to match the Buck Mark’s style
Made from aluminum and hard anodized, the rail blends in well with the finish on most Buck Mark models. It fits a compact light or laser perfectly—long enough for accessories, but short enough to avoid adding bulk or unnecessary weight to the pistol. The rounded profile and beveled edges keep it from snagging, and the added weight is barely noticeable. On top, it’s low-profile enough that it’s not going to interfere with sights or optics.
More practical than tactical
If you need to add a light for small varmint or pest control, this upgrade delivers. During testing, I mounted my Streamlight, which is compact, but still has decent output. The rail kept the light locked in place with no loosening or shifting, even after multiple range trips. Between the light and my suppressor, the weight of the Buck Mark under-barrel rail is insignificant.
Why this Browning Buck Mark rail matters
There’s no shortage of aftermarket parts for the Buck Mark, but under-barrel accessory rails are rare. This rail fills that gap, and does it in a way that’s simple, functional, and completely reversible. For those who already run optics up top, this opens the door to new configurations below. And it helps close the gap between Browning and Ruger when it comes to aftermarket support.
Final thoughts
Performance Services LLC clearly understands what rimfire shooters want. Their $59.95 (+ shipping) bolt-on under-barrel rail for the Buck Mark offers a practical, well-executed solution for adding accessories without altering your pistol. It’s a subtle upgrade that adds a lot of value, especially if you use your Buck Mark for more than just punching paper.
