The EALM100 Lo-Mount was specifically designed to attach a Compact Trijicon Scope to an FN PP90/PS90 weapon system. Trijicon ACOGs are fitted on tactical rifles by many civilian and military personnel because of their rugged, reliable performance. Existing rail mounts place the ACOG sightline uncomfortably high. The EALM mount will allow you to mount your Compact ACOG in a more natural sight plane making it much easier and faster to acquire a target. If you have an ACOG on your other rifles, now you can keep that same familiar sight picture. The mount is manufactured from aircraft grade aluminum and black anodized to make it a durable, corrosion resistant addition to your weapon.
