Frequently asked questions
What is the magazine capacity of the LAR-BT3 Varmint?
This rifle is configured with 20+1 capacity—20 rounds in the magazine plus one in the chamber. Magazine restrictions in your jurisdiction may apply, so verify local requirements before purchase.
Is the 1:10 twist rate suitable for standard .308 ammunition?
Yes. The 1:10 twist handles typical .308 rounds reliably. This rate is also ideal for heavier match-grade ammunition if you're pursuing precision shooting. Test your preferred loads for best results.
