I'm just getting into shooting for more than hunting and was looking at a used scope for my Rem 308 Police rifle. A local shop has a used 5-15 Bushnell 3200 Elite AO with the mil-dot reticle and the tactical turrets for $275. This is the older model 325154T and not the newer et5154. Is this a good price and a good scope to start out with? Any help would be appreciated. Thanks
