The Bergara HMR Trainer (B14R) is a left-hand bolt-action .22 LR rifle built on a synthetic molded mini-chassis stock with a matte black and gray finish. Barrel is 18" and threaded 1/2x28. Capacity is 10+1. Weight is 9.25 lbs, heavier than most rimfire rifles because it's designed to replicate the feel of the full-size B14 HMR centerfire chassis rifle. The receiver is drilled and tapped for scope mounts, and the trigger is adjustable for pull weight.

Usage Scenarios 

1. Training transfer. The B14R is intended as a low-cost trainer that mimics the ergonomics and feel of the B14 HMR centerfire. Shooters who run the HMR in a larger caliber can practice fundamentals with cheaper .22 LR ammunition. 
2. Precision rimfire competition. The chassis stock, adjustable trigger, and threaded barrel make this competitive in rimfire precision shooting formats. 
3. General range use. 18" barrel and bolt action are well suited to deliberate, accurate shooting at longer rimfire distances.

The B14R consistently earns positive marks for accuracy. Owners report tight groups at typical rimfire precision distances, and the adjustable trigger is called out as a genuinely useful feature rather than a token one. Build quality gets similar praise. The chassis stock feels solid and the action is smooth.

The weight is the most common criticism. At 9.25 lbs the B14R is heavy for a .22, and shooters who expected something light for all-day carry are sometimes surprised. That weight is intentional for a chassis-stock trainer, but it's worth knowing before you buy. Price comes up too. The B14R costs more than most rimfire bolt guns, and some buyers debate whether the trainer-specific justification is worth the premium for their use case.

Left-handed shooters in particular appreciate having a quality LH-configured rimfire option at this tier, since the market is thin. Customer service from Bergara is described as positive by most who've needed it, though a few have mentioned slower-than-expected parts turnaround.

Overall the B14R is well-regarded among shooters who specifically want a precision rimfire trainer that matches the HMR platform, and receives solid marks from anyone who prioritizes accuracy and build quality over weight savings.
