The Browning X-Bolt 2 Speed SPR is a bolt-action rifle chambered in .308 WIN, designed around an 18" fluted barrel that makes the package four inches shorter than a standard sporter configuration. The shorter barrel is optimized for suppressor use. The belled muzzle threading (5/8"-24) accommodates larger diameter suppressors, and the radial muzzle brake is included for unsuppressed shooting.

Features 

 
The Vari-Tech composite stock has three-way adjustment for comb height and length of pull, which matters when you're fitting the rifle to a suppressor-height scope.

Rubber overmolding on grip surfaces maintains control in wet conditions. 
 
At 6.3 lbs, the X-Bolt 2 Speed SPR is on the lighter side for a .308 bolt gun, which you'll notice carrying it all day.

The X-Bolt Gen2 SPR in .308 Win draws generally positive owner reviews, with accuracy and handling being the most-cited strengths.

Out-of-box accuracy is the first thing most owners mention. The rifle tends to group well without a break-in period or load-chasing. At 6.3 lbs it handles easily in the field, and the 18" barrel keeps overall length manageable in tight cover or a vehicle. The trigger gets solid marks for feel and the ability to adjust pull weight without a gunsmith. Build quality and finish are well-regarded, with the OVIX camo holding up to field use. The suppressor-ready threading and larger muzzle socket are specifically mentioned by hunters who run cans.

.308 recoil in a 6.3 lb rifle is noticeable; a few users find it more than expected and recommend the muzzle brake or a suppressor to take the edge off. Magazine feeding issues come up in a small number of reports, not a pattern complaint but worth knowing. Price sits in the premium hunting rifle range, and most owners feel the quality justifies it, though the debate continues. Overall the SPR has a solid reputation as a practical, well-built hunting rifle that works out of the box.
