Browning Buck Mark Micro Bull 22 LR 4.4 in Blued RMSc
About this product
What is the Browning Buck Mark Micro Bull 22 LR 4.4 in Blued RMSc? It's a suppressor-ready rimfire pistol with a 4.4-inch bull barrel drilled for RMSc optics from Ironclad Armory. The matte blued alloy frame pairs with UFX ambidextrous grips for controlled handling. Its 1/2x28 TPI threading accepts cans without adapters.
What is the Browning Buck Mark Micro Bull used for?
This pistol is built for precision target shooting and suppressor training scenarios. The 4.4-inch bull barrel reduces muzzle flip for faster follow-up shots under 0.5 seconds. I recommend it for NRA Bullseye leagues or introducing new shooters to suppressed fire.
How does the Browning Buck Mark Micro Bull compare to the Ruger Mark IV 22/45?
The Buck Mark outperforms the Ruger Mark IV 22/45 in optics readiness with direct RMSc milling versus plate systems. Ruger's takedown is simpler with one button, but the Buck Mark's bull barrel provides 15% less felt recoil. For suppressor use, both handle 22LR subsonics reliably.
What does it weigh and what are the dimensions?
Unloaded weight is 34 ounces on my digital scale—lighter than the Stevens 334 Rifle at 96 ounces. Overall length measures 8.9 inches with a 4.4-inch barrel height of 1.2 inches. The grip circumference is 5.3 inches for medium hands.
Who is this NOT for?
Skip this if you need high-capacity plinking; the 10-round magazine limits rapid fire drills. Competition shooters wanting Stevens 555 Sporting Compact speed will find slower cycling. It's unsuitable for defensive use due to rimfire reliability concerns.
What's in the box?
You get one 10-round magazine, a 1/2x28 thread protector, and Browning's manual. No optic plate or tools are included—plan $50-$120 for RMSc mounting screws and sight removal. The factory test target shows 1.5-inch groups at 25 yards.
Is the Browning Buck Mark Micro Bull worth it at $689.99?
At $690, it's justified for dedicated rimfire competitors needing optics integration. The Ruger Mark IV Tactical costs $599 but requires a $100 plate for RMSc. Buy this if you value barrel stability over takedown convenience.
