I'm a cheapskate...so I end up getting inexpensive scopes and discovering what works well and what sucks...
TASCO...just run away...never had one last more than two years...and I'm really not that hard on scopes.
BSA...depending on the model, either do great or total suckage...
Simmons...liking these more now than I did a few years ago...they've come a long way on their less expensive lines...
Redfield used to make some great inexpensive scopes, but they're more in the $150+ range these days...
Centerpoint...One Huge thing to know about CP scopes with locking adjusters...
Do NOT move the adjuster without UNLOCKING the locking rings...otherwise you break the adjuster and it won't ever hold zero again...
Lots of schmucks didn't read the instructions, and destroyed their scopes the first day...so never get one from a pre-opened package (a return).
Other than that, they work GREAT!! My 4-16x44 mildot red/green reticle scopes are champs!!
For around $70, you just can't beat 'em!! Also have a pretty good warranty...so for those who broke theirs...send 'em in!!
The only thing I like better than a CP...NIKON & Leupold...but you'll pay for those...and I'd rather spend it in ammo
