I bought this for the specific purpose of being able to mount a light at 12 o'clock forward of the sight base on a rifle I'm not allowed to make "permanent" mods to. It works perfectly for that purpose. Not solid enough to mount sights or aiming lasers to. Only reason for the 4 is it springs back against the delta ring about half an inch with very little effort. Kind of distracting if you aren't expecting it.

Solid piece of hardware. This AR-15 Quad Rail is well built. However, is not for piston-driven (e.g. Adams PS) AR-15's. I do however, recommend this quad rail for non-PS, direct-impingement/gas-tube AR-15's.

Found out the hard way my new LAR-15 Entry Tactical has a second front swing swivel on the side of the A2 Sight/Gas block.Since there is no cutout for this in the rail system, it would not fit on. Removing the sling swivel required drilling out a rivet. Had to return and order the short guard that does not extend past the front guard ring.

Bought this for my DPMS AR 15. Looks great and fits perfectly! I am pleased with this and the excellent service from Optics Planet. They went above and beyond to accommodate me. Thank you Optics Planet!

I looked all over for a rail system like this.. Prices ranged upwards of $80. I didn't want to pay that amount but saw this one at optic planet for $54.99. So I plunged. I have a SW mp15 sport. The original fore grip was awful. I replaced it with a magpul which again I didn't like.. it didn't fit properly yes it the SL which is too big for the MP 15. This Arrived today .. far more quickly than I expected. It was incredibly easy to fit and looks great and feels far more solid than those resin grips. It is really well made and fits perfectly!
