Scoping an AR-15


February 24, 2007, 05:54 PM
I just recieved the RRA LAR-15 flat top that i bought from Equalizer (off of this forum) today. I already have a 4-12x40mm Fujinon scope and a set of Durasight Z2 Q/D rings to mount the scope with. The problem is that i dont have the clearance or scope height to comfortably look through the scope. So my question is should i buy a higher set of rings or should i buy some kinda spacer? Im lookin for suggestions from people that have dealt with this before. I would also like to have some product suggestions. Thanks.

I advise against getting super-high rings. In order to get the correct height over rail, you'll need very high rings. That makes them less sturdy or rugged as a result. Unless you spend around $140 or more and buy heavy duty all steel tactical rings.

Getting a rail riser has a big advantage, in that it allows you to use regular rings. The biggest advantage is that it brings up the entire range of heights for a given ring set. So, you can buy low, mediums, high or extra highs depending on what you like because the riser rail gets them in the ball park height-wise.

For example, Leupold high rings are too short for an AR. Burris high rings are way too short. No ring set is the same as others as there's no standard determining what is high, med, low.

A riser helps a lot.

A good riser, for a good price that is solid is the Yankee Hill one piece:
Third item down:

There's also this rail riser that also moves the scope forward if your scope has good eye relief (like 3" or more) ...


You can buy 2-piece risers too. ARMS makes one piece risers, as do a lot of others, but these are 2 good ones that are inexpensive, yet solid.

If your scope has 30mm tube, you can buy tactical rings which would do the job. They look like this:

Paco, are you pokin fun at my scope? Ill guarantee its cleared then tasco and bushnell. So far i rank it with my baseline leupolds.

Dont Tread, do those yankeehill pieces have anything to protect the ar reciever from the screws that hold it into place from marring up the reciever?
