Question: what is the warranty?
Document: Adjustment is easy and very clear. I can focus it more closer. Warranty is lifetime and Simmon brand is respectable.
whaited over 15 days for simmons scope only to receive a tasco scope instead. I didnt want to mail it back, who knows what they would have sent me next. NOT A HAPPY CAMPER.
this scope would be great on any rifle....50mm for the light gathering is what i wanted..so i  bought two of them.ruger american 243 and 50 cal black powder...
for the money can't be beatSimmons best in price quality and functionI have owned several Simmons scope and this is the best one yet
Works great on my .177 air rifle. Anything else for smaller rifles is just for show. Will buy again for all my plinking
Within a dozen shots or so, I was grouping about 1 inch while resting the rifle on a bench. Doubtless, in a good benchrest, the rifle would group a little better.The glass looks clear and crisp to me. Granted, it's not a $1000 scope and doesn't pretend to be one. But, for what I wanted, it looks good. My brother-in-law told me he had this exact scope and it did not hold up on his .45-70 handi rifle.
When I bought the scope I knew it was not a high in scope. It workers for me so I am ok with it.
We did all the above to discover that the receiver had moved. So UPS found them only to have them refuse the package. They "Don't want it!" Therefore I cannot give the scope or the Simmons Company a very good review.
Very very accurate scope for the money and never miss a target at all. I hunt every year in California for Grey Tree Squirrel about every shot is at a range of 30 to 60 yard & was head shot clean out of my Ruger 10/22 & CCI stinger or velcitor ammo... great price for the scope is a must have scope I drop it on the ground so many time when hunting and never miss a shot...
UPDATE: 12/5/12****Don't buy the scope! Originally I was shooting my 30/30 at 1" groups at 100 yards, BUT now the picture is blurred after a dozen rifle fires. Basically if you want to put this on a .22, go ahead but don't try it on bigger rifles.I was very skeptical about this scope (especially because of the price and that I was mounting it on my 30/30 which kicks like a mule).
Answer: yes
