Question: I have a Glock 19 Gen4, the rail has only 1 slot at end of barrell which makes my light extend too far forward.  Will this riser fit my gun?
Document: FYI this does not work on DPMS gas blocks to even up w/ the rail. Its about 1/8+ to tall and the sights will not line up! UTG makes a front flip up sight that is incredibly inexpensive and fixs the problem. Amazon sells it and its a great sight at a fraction of the cost of the YHM.
Worked on the side rails of my hand grip as a &#34;riser&#34; for a light and/or a laser if wanted. Very light weight. Re-install took about 10 seconds. Solid on the rail. I don't like a lot of things sticking out to the side, but the wing nut is pretty standard, and except in closest contact, didn't hook on anything. I can recommend it.
This riser worked better on my Core upper/USM4 lower AR15 than the taller QD version. Each gun can have a different gap, and the gas block height is as important as the receiver-to-barrel top rail's height. On my gun, this fit better, and though not a QD (quick detach), unscrewing the wing nut and removal only took about 7 seconds max.
I have a Primary Arms Micro-Dot #6 that comes with a low mount. When mounted on a flat-top AR15, it was not quite ergonomically correct... putting the dot at above 2/3rds high with a proper cheek-weld. By adding this 3-slot riser, it brought the dot down to about 1/3 high.... perfect!
I put this on my dpms oracle. Fits great but my only two complaints is that it is higher than the quad rail by about a 1/4 inch. Does not sit flush with the rail and my magpul flip up front sight will not flip up when mounted on top of this riser.
I actually bought this for a cheap riser for my gas block rail, and while it's a little taller than what a gas block rail riser is supposed to be, it still does the job great. I believe this make the front sight 1/8&#34; higher than the rear to start with, but since I can adjust the front sight's height, it's really not an issue. I'd rather deal with this than pay $30+ for another brand's specific item.
This riser mount is built well- the spring-loaded turn key keeps it tight, and the rails are high quality on top and bottom.THIS WILL NOT WORK WELL FOR THE DPMS ORACLE A15. The low-pro gas block is an odd height on the DPMS, and this riser is approx 1/4 inch higher than the receiver-mounted rail system.
excellent fit and finish...easy on and off..turn knob tightening makes for easy in the field usage. cant beat the value and workmanship
i wanted a sight for my paintball gun but it wouldn't fit cuz of the bolt so i got one of these to raise it but oh was i wrong. it raised it but now its soooo loose it just wobbles whenever i aim down the sight due too cheap manufacturing
Well other reviewers warned me, but I bought one anyway, and had the same problem. My mini red dot is 1/8&#34; wider than the rail, and the wing nut hits it and won't turn tight. Other than that, this thing is impressive. Well made, and the little springs that spread the clamp mechanism are a nice surprise.
Answer: yes
