Question: Will this work with Magpul flip up rear site and 'F' Marked Front Sight?
Document: The description says that the AR model (with high mount) will "co witness" the flat top AR front sight. It might with the stock AR front sight but I have an MI flip up sight (the shorter one) and it does not co-witness. The red dot sits significantly higher than the front MI sight post.
Solid construction, easy to mount, although it should be noted that with a carry handle you will need the low ring mount. And while it will co-witness with the carry mount, you will likely not have room to use the magnifier. A flip up back site would fix this issue(then you will need high mount).Easy to sight in. Adjustments give solid clicks and once zeroed, holds center very well.
Interestingly enough, when I flip up the rear sight for co-witness, much of this starburst effect disappears for low to moderate brightness settings. 3) The scope view has a greenish tinge that is noticeable, but not a serious detriment. 4) Although the Strikefire is said to be parallax free, I do notice some dot movement between 50-100 yards, but virtually none beyond that.
Other note, the are two different mounts. THe hunting version will not co-witness with an A2 front sight - it is a lower mount.
Very nice red dot sight that actually cost less than my rifle. After searching for weeks for a red dot sight that didn't cost $600-1200 I decided on the Vortex Strikefire and have been bery pleased that I did. This sight seemed to have by far the best reviews of any red dot that was nog ACOG. Mine is attached to an AR-15 in 5.56. I used the tall sight mount that came in the box as I keep the original iron front sight on my rifles.
This sight is on par with the Aimpoint RDS for 1/3 the price. I have some experience using the Aimpoint RDS and have to say they are eerily similar in design. Quality is very good with a strong picatinny base and the tude construction is sound. The flip covers are rubber causing them to unneccessarily flip up if not pushed down but thats not a problem.
One third the price of an Eotech or Aimpoint, this sight works just fine for a budget AR15. It sighted in easy and holds to zero,no problem. 500 rounds fired so far with no trouble. The times two magnification attachment is less than stellar but it does work. The sight itself on the other hand works like a charm, more than worth the money.
I have a feeling these folks were used to a system with a snap switch configuration. The lids on this sight are basic rubber lids that mold around each end. Not hard to close at all. Just hard when compared to other systems out there. The lids were easy to flip open with a single finger (point is, when the situation calls for it, as long as you can quickly deploy your sight, you're fine.
My first Strikefire had a bit of an issue, but Vortex quickly resolved the problem and it now works perfectly on a tack-driving Ruger 10/22. What a "blast" to use this sight. Yes, the lens caps are tight, but instead of fighting this and complaining, I found that less than 30 seconds with a Dremel stone on each cap makes them work perfectly!
The flip covers are able to rotate 360 degrees allowing the shooter to position the covers where ever comfortable. It is wide due to the function controls and the battery and long with the doubler. The co-witness between ironsight and dot is great for any folding and standard sights. Overall this is a great sight for the price and I intend to thoroughly test and train with it for many weekends at the range.
Answer: yes
