PRI Riser/Extendo Rails?

[redneckbmxer24]

Has anyone used the PRI riser rails? Looking at this one:

PRi AR15 / M16 Top Rail Riser 2 Hole With 20 MOA

The 2 hole Rail Riser mount was originally designed to set on the M4 flattop receiver but it has proved to be a versatile base for many different purposes.

I've got an optic in 1.125" height rings that I want to leave in to use on a hunting rifle a month out of the year but otherwise live on an SPR. Figure this may be a decent solution to swap with two nuts vs having to remount an optic. They have a 3 bolt version too but it's not available in 20MOA which I'd prefer.

Any issues from those who have used them? I'm not interested in feedback on other brands unless they are at least the quality of PRI. If someone knows of a better riser and has experience with it I'd like to here, but these are all I found other than the thumbscrew chicom junk that doesn't extend over the forend which I need as well.

I have the three hole (I think, might be two hole 0 MOA?) sitting in a parts box downstairs. Used it flipped backwards to get some height under a short eye relief optic I had on one of my small frames. No real complaints, if it meets your specs there’s nothing wrong with it.

I did at the same time have a KAC riser that was better constructed, but finished worse.

Does it have built in recoil lugs? I can't find any pics of the under side of them or mention of lugs. I know the YHM one doesn't, I had one of them and it sucked hard.

I found a couple pics of the PRI on rifles and the 2 hole has a lot of overhang. I think I'd actually go with the 3 hole for more rigidity and sacrifice the 20moa.

I’ve used similar rails for extra height. As long as its torqued down good there is no issue.

I have quite a few of these, never tried the PRI 2 screw.

My EGW ones have all bee rock solid.

On my three hole it doesn’t have any recoil lugs, it’s just using the three cross screws to achieve that.
