Leupold vx-r patrol 1.25-4x20mm 30 mm tube and american defense ad-recon-5 qd mount - Leupold VX-R Patrol 1.25-4x20mm Illuminated Riflescope

I have used Leupold scopes for over 40 years, both tactical and hunting scopes on My Department Robar Sniper Rifles and on my personal Tactical and Sporting Rifles. I purchased this scope utilizing an American Defense AD-Recon-5 Mount and placed the combined system on my Springfield Armory .223 Saint "Edge" Rifle. Everything has come to the level I would expect from Leupold, with the exception of the illuminating fire dot. On the first three settings the fire dot is fine; however as the fire dot intensity is increased the dot becomes more of a elongated burst or flare and it looses its symmetrical shape,and centered position in the reticle. I have tried this under several light conditions both day and night I have also had 2 - 3 associated check the scopes and they have all observed the same situation with the fire dot. Thus the grading of four stars is given! All other factors about the scope are excellent!
