Question: Would it work to mount these sights on a DPMS 260-LR under the scope mounted with see-through scope mounts?
Document: This product has good tension on flip up and flip down. I mounted a scope, and charging handle extension, (MY BEST MOVE). The scope is a BDC 600 Nikon AR P-223 on a 5.56/223. These are not the best out there but they will get you on target and they do work good. If you want to use flip up sights, I would recommend these.
I got them for my new DPMS Sportical that I got from Wal-Mart which did not include iron sights. Went on easily and they work very well. I'll mainly use the scope I put on the rifle, but wanted back-up sights that weren't too expensive. These are very good.
PROS: If you want a dirt cheap site that can 'act' like a backup site, these will workCONS: These are poorly designed and more poorly implemented. The rear site would not lay down for me at all. When I finally did get it to lay, the 'flip' part of the site prevented my scope from backing up enough for proper eye relief. I could have gotten high rise mounts, but with high rise mounts why would I not just have normal sights?Overall, was just very disappointed.
Bought these BUIS for a DPMS Sportical from Walmart, as it came sans sights. Happy with build and fit & finish, mounted with no problems to the upper's rail and gas blocks rail.If I had wanted an AR for "the road", I would have gone with a Spikes Tactical LE M-4 with Troy, MI, DD or Magpul sights, but I wanted a plinker to play with and the Sportical fits the bill, and these BUIS were the perfect addition.
they do flip down to easily and the adjustment knob seems a little flimsy. Next time around would probably buy something better. Mounted them on a DPMS oracle ar-15, flat top receiver.
The windage does click and seems to stay locked, although I never even made it to the range with these to see if that remained the case under firing conditions before I returned them. You simply cannot shoot straight with bent sights. These sights would probably work just fine for toys or airsoft, but I would not bet my life on them in any kind of field condition on a real gun.
I bought these sights before I had received my new upper. I wish they didn't sit so high because I will now ahve to buy a 1&#34; riser so I may mount a scope thay will clear these sights. I haven't put any rounds down range so I don't know if these sights will hold up
I wanted something not to pricey to use until I got my scope the mount quick a so far stay tight
Well, excited, then disappointed. Put these on my DPMS Oracle..... The front sight mounted fine on the gas block rail, but it has to be put on backwards because it won't fold down onto the guard. So the front and rear sight release buttons are on opposite sides. Not really a big deal. But the rear sight won't lock into the down position.
Buyer beware, what I received was totally different from the picture. The sights I received came with no instructions, are loose and do not stay down. I am debating on returning them right now. I may try to take a trip to range to see if they are worth a hoot.Read more reviews from this seller, you will see other people saying the same thing; I wish I would have seen those reviews.
