Question: how long is this scope...and will it hold zero on an article 15
Document: This is a very nice scope, and holds 0 very easily. The illuminated crosshairs make it very easy to see the target at twilight times, or when there are dark backgrounds behind the target. The only reason I didn't give it 5 stars was the fact that when the zoom got up to 15-16 things got a little unclear. I used this with my Gamo Silent Stalker, and the scopr mounts that hold the stock scope also hold this scope.
I found what was left of him and it was a solid neck shot. Apologies to lizard lovers...but, I promise, he never felt a thing. )As with any magnifying scope, it not only magnifies the target, it magnifies your every move, including heartbeat! It lets you know just how much wiggle there actually is in your hold!As for the zero locking turrets, the instructions are very vague...actually, they barely even mention it!
Have a Gamo Bone Collector IGT Bull Whisper.First tried BSA Essential 3-9x40 Scope. Could not hold zero. Moved/shifted zero all the time. One day difference the other day. Every time difference. Frustrated!Second tried UTG/Leaper, it was said the best by some reviewers. Not really true! One has many &#34;dots&#34; inside the lens, and the other range ring (Objective Lens Adjustment Ring) fell off after a couple of rounds.
More solid looking. Hold zero!!! No more worry the zero shifting. A couple of hundred rounds now, still good. Time will tell...Best so far.
At first i thought the illuminated crosshairs were a little gimmicky, NO ! in low light these are fantastic ! When plinking recently i easly shot 15 minutes past everyone else as i could still see my targets ! I can also tell you that Centerpoint & Sniper are both the same scope with a different name stamped on them. This scope can also be found at walmart for $69.98  if your shopping for small arms, have no fear with this purchase.
Unfortunately this thing did not hold up to my .25 Hatsan Mod. 125 air rifle.It only took about 20 shots before this thing had cross hairs bouncing all over the place.On a .22 it would be great! This thing has alot of features packed into a very affordable scope. Well worth $150
all you simply have to do in this case is shoot a few rounds and the recoil usually frees it up.Everything was working fine then suddenly it started becoming erratic and placing pellets all over the place. I could not hold a decent grouping. I normally would think it was me, the pellets or the rifle, but it was fine for a while and nothing changed. That is until I looked through the scope again and noticed the the center of the crosshairs were split.
This first one I bought was a complete POS, I purchased this from walmart for 69.99. I returned it and gave it a second chance. Its perfect now! Comes with mil-dot, Blue/black/Green reticle, flip up covers, turret system 15-200 and infinity parallax, and nice ring mounts.
the only real downfall is the weight, but, I'm a big guy so a few extra ounces doesn't really bother me.This scope holds zero very well, as another review said i have dropped my gun and don't need to rezero.By all means, if your into competition shooting or are a sniper that shoots 500+yrds there are better scopes on the market, but, not at this price point, or even double this price point.
I brought my scope and put it on it and he zeroed it at 300 yards ,it took him 8 shots I think. But we both shot 20 rounds through it and it held its zero we both thought for sure it wasn't going to work. Now I still have it and haven't gotten a new scope. After testing it on a .50 and no problems I can say I would pay $500-$600 for this scope.
Answer: yes
