Dave's Review of EOTech Model 558 Holographic Weapon Sight
The sight experiences thermal drift. I did not know that this happens until after purchasing the sight and after hearing it could not believe it was that bad. It is very bad if you sight the summer then use it in the winter it will be off by inches at a 100 yards. Went shooting in July and the sight was dead on. Come winter I went shooting and it was 30 F and it was sighted in left 3 inches and low 2 inches. I can not understand how EO Tech is still in business. The drift is very real and very large.
Pros:
- easy to use.
Cons:
- Easy to loose zero.
Best Used for:
- On your enemies rifle.
Would Recommend:
No
