Have a Henry Mini Bolt. Purchased primarily for my grandson, but both my wife and I love to shoot this nifty little rifle.
It was designed as a 'youth rifle' and weighs just over 3 lbs. The design is excellent for the intended purpose and is fun to shoot for adults.
Rear bolt lock up. The lock up is completely tight after the action has been cocked by the cocking piece.
Accuracy is fine,especially given the light weight and short barrel (16.5"). Trigger as good as one could expect on anything less than a target grade rifle (considerably better than an out of the box 10/22). I have not bench tested it for accuracy, but there have been no bad surprises shooting it at paper, balloons, and silhouettes at 15 m to 25 m standing.
The fibre optic sights are great, especially for new shooters.
To mount a scope you can get a base which Henry makes particularly for this rifle. I recommend the Mini Bolt - very nice little rifle. Check out the owners' letters on the Henry website.
