Superb for 9x19, 5.56 & 7.62 nato - Sun Optics 4x32 Tactical Precision Prismatic IR Scope

I first purchased this for my HK91 chambered in 7.62mm NATO and used it with an elevated Scope Mount to allow use of either the Scope or Iron Sights. After getting a new 3-12x44 IR Scope for long distances, over 300 Meters, this 4x32 Sunoptics Scope found itself on my HK93 chambered in 5.56mm NATO. After this Rifle adopted a different Scooe, this Sunoptics 4x32 has happily found a new home on my BCP-EF9,an AR style Pistol with an 11 Inch Barrel chambered in 9x19mm NATO. With both HK Rifles using the elevated Scope Mount and an elevated Cheek Rest, this Sunoptics Scope did well regarding the Eye Relief. However, it is absolutely amazing with the 11 Inch AR style Pistol! This Firearm is designed as a Close Quarters Battle Personal Defense Weapon (CQB-PDW) and usually wears a Red/Green Dot Sight for quick targeting,being able to group within 3 Inches at 25 Yards. But with this Sunoptics 4x33 IR Scope, fired from a Prone Supported position, my 9mm AR style Pistol groups within 2 Inches at 50 Yards. And on this low recoil 9mm Firearm, the 3 Inch Eye Relief is absolutely perfect!
