Manufacturer claim
- XCaliber Firearms lists the Mountaineer-D at $650.00.
- Sound pressure levels on 7.62MM hosts range from 134 dB to 136 dB, and 131 dB to 134 dB on 5.56MM hosts.
- Mountaineer-D: 8.5" overall length, 1.5" outside diameter, 28 oz.
- XCaliber: the core system is upgradable, and most companies seal or weld centerfire rifle units so they cannot be upgraded — by not sealing our units we can offer upgrades in the future at minimal cost and time.
