This Weaver Extended Multi-Slot Tactical Picatinny-Style Base is just what you need for your rifle. These bases are constructed of aluminum, so they won’t add much weight to your rifle, but they are strong enough to withstand the heaviest recoil. The multiple slots provide you with plenty of space for mounting optics and allow you to position your scope for optimum eye relief. This base has 20 MOA built in to allow for shooting at longer ranges.
