Detailed Features 

The straight-pull mechanism cycles without rotating the bolt handle, which keeps the shooter's grip on the rifle and allows faster follow-up shots compared to a conventional turn-bolt. The 20" bull barrel adds mass for stability and reduces the barrel harmonics that affect group size. The threaded muzzle accepts standard 1/2x28 suppressors directly. The satin walnut stock has a raised cheek piece and point-pattern checkering; the adjustable gold-plated trigger lets shooters set pull weight to preference.

Shooters who pick up the T-Bolt Target SR consistently mention the precision it delivers in .17 HMR, with tight groups reported at typical rimfire distances. The straight-pull action gets credit for smooth, quick cycling. The lightweight at 6 lbs 2 oz makes it comfortable to carry during extended field sessions.

The main topic for improvement in user discussions is trigger feel — most find it acceptable but some want a crisper break. Aftermarket support is thinner than for more common rimfire platforms, which comes up occasionally for those wanting to customize beyond the adjustable trigger.
