Available in a variety of calibers based on the .308 case, it offers repeatable accuracy so that the shooter can be confident that, when he puts the rifle together to make the shot, the bullet will be launched with the gun in the same condition as when he zeroed. For example, working off of a barricade is a much easier proposition if the gun is wearing the optional barrel sleeve, and this also gives the ability to add clip-on night vision devices via its top rail. Our test rifle arrived in a fitted hard case, with the gun taking up about 2⁄3 of the available space leaving plenty of room for even the largest optic.
