The NPTech 881 Holographic sight is a replica of the EoTech 551, a very popular choice within airsoft for an optic.
Whether you play indoor or outdoor the NPTech 881 makes it easier for target acquisition and its limited parallax makes it easy to get a good sight picture. The sight also has adjustment for windage and elevation making it possible to zero the rifle with the scope added.
The sight will fit onto any 20mm RIS rail making it compatible with a huge range of airsoft guns and with its elevated design it can make it easy to use even with a lower face mask. The sight can be adjusted from a red dot to a green dot for night use, this makes it an adaptable scope for a range of situations.
