Nicely done. You will certainly see those groups tighten up with a scope, and your numbers are significantly better than the average person shoots with a red dot (are you currently rocking an Eotech?). Under 2" group with a 3x and dot is impressive at 100. BCM makes quality parts; their rifles are capable of shooting MOA or better for the most part. Let us know how it goes with the scope and match ammo!
Looking forward to hearing how the scoped shooting goes!
