UTG Medium Profile Compact Riser Mount, 0.83" High, 3 Slots , MNT-RS08S3 Excellent ergonomics is always a desirable trait for shooters and outdoor sports enthusiasts. A comfortable shooting rifle not only puts less strain on the shooter, reducing fatigue, but also keeps the user safe by not forcing him/her into an improper shooting form or stance that could lead to other problems or injuries. A proper cheek weld against the stock is a fundamental basic, but is not always achievable when you take into consideration the different varieties of optics that are often used with these rifles. At times, optics may sit too low or too close for users to gain a comfortable and secure cheek weld. Leapers UTG riser mounts are the answer and are the ideal accessory to bring your optic to the most comfortable and safest shooting height. By the way, don¡¯t forget that selecting one of these riser mounts also allows you to get that perfect or 1/3 co-witnessing you desire with iron sights for your optics.
