Dead-Hold BDC MOA Reticle

  • Customized hashmark design helps eliminate guesswork on holdover and windage corrections. Good for hunting/shooting at varying ranges where estimating holdover is a concern.
  • Second focal plane (SFP) reticles are located near the scope’s eyepiece behind the image erecting and magnifying lenses. This style of reticle does not visually change in size when you change the magnification. The advantage of an SFP reticle is that it always maintains the same appearance. Listed reticle subtensions used for estimating range, holdover, and wind drift correction are only accurate at one particular magnification.

Customers are mixed about the brightness of the aiming scope sight. Some mention that it has lots of light, excellent light capture, and is great in low light conditions. However, others say that it's not an illuminated scope, the red-dot in the center is not very bright, and gets washed out very quickly. The light collection is so-so, and shooting at dusk or dawn with this will probably be a problem.

Awesome Budget Rifle Scope - very clear optic and great eye relief
5 Stars
Awesome Budget Rifle Scope - very clear optic and great eye relief
4-12x40 AO Scope = First, you are not going to be looking through the "soda straw" effect with this scope. It has great eye relief of about 4 inches and a great eye view quality of very minimal scope black eye ring in your sight picture. You get a great view with full image at low and high power in this scope. It has an Adjustable Objective and the reticle is very clear at 2nd focal plane use. It is to be used at 12x and if you are going to use that BDC, you need to be prone or in a very, very stable shooting platform position while at 12x to use this BDC. The turrets are fine and are capped. I do not trust them for dialing up and down MOA. There are box tests I have seen where they performed fine but this isn't a $1000 scope. This is a budget hunting scope with a nice BDC that can be used for ranging mixed with a ballistic calculator for holdovers and doping the wind out to what I consider 500 yards use. It has more than enough magnification for that and I have taken mine out to proof it shooting steel rams at 500 yards with no issues off my bipods. I ballistic computer matched the reticle with an accurate handload and it is good out to 600yds on my rifle. If you are just shooting to 400yds, I recommend the 3-9x40 BDC Crossfire II scope for hunting. If you are shooting varmints or shooting out to 500yds, the 4-12x40 AO is what I recommend. The Vortex Crossfire II is a budget hunting scope that would fit nice on a Savage Axis / Ruger American Rifle for a budget rifle optic. I've attached some BDC information on this scope to look at the values. This is great budget glass for a budget rifle setup. If you are shooting 500 yards and under, this is really all you need. If you are going past 500yds, you need a better quality scope for dialing the scope turrets / wind values, custom rifle, handloads, etc. more time & $$$$.
