You asked we listened. The Bergara BMR (Bergara Micro Rimfire) is for those that demand the best and expect nothing short of perfection. With the option of either a 5rd magazine for hunting or a 10rd magazine for running stages at your favorite rimfire match we designed the BMR from the ground up with field and match performance in mind. - The BMR fits the bill of the base class within the NRL22 series and offers a match chamber with world-class accuracy. It�s also lighter (especially the carbon barreled version) and easier to carry in the field for small game pursuits. We�ve expanded the calibers available beyond .22 LR to include .17 HMR and .22 WMR so you can match your round to your application. - Some features that make the BMR stand out: - Action: BMR - Barrel: 4140 steel matted blued finish. No. 4 taper - Twist: 1:16 for .22 LR and .22 WMR and 1:9 for the .17 HMR - Barrel length: 18� (.22 LR) or 20� (.17 HMR and .22 WMR) - Threaded muzzle: 1/2-28� with thread protector - Weight: 5.5 � 5.8 lbs. depending on caliber - Length: 36� or 38� overall - Mag capacity: 5 and 10 round magazine included - Scope mounts: 30 MOA Rail Included - Trigger: Bergara Performance Trigger.
