"Has the extended top rail to cover the delta ring, which looks awesome. Finish is nice, fits snug on my DPMS, has four tiny Allen screws to prevent moving. The best part was the price."

"Excellent choice for the price! The top rail covering the delta ring does look amazing, and lines up nearly perfectly with the receiver rail. Only reason I gave it 4 bullets instead of 5 is because the Allen screws are a hair off in location; the bottom section locks perfect, the top section the set screws don't wedge against the barrel nut too well, as they start to skip over the inner edge of the nut. I drilled and tapped these holes for one size larger set screws and it now is perfect and locked solid."

"I was looking for a quad rail without having to pay $200 for it. I liked the extra space over the delta ring which IMO makes it look better/cleaner.So far it seems tight on my carbine, though I haven't tried it out on the range just yet."

"I too was searching for a quad rail handguard that wouldn't break the bank. Diamond USA was over $129, thank goodness I hesitated on pulling the trigger on it and found this instead. $56.75 door to door. It took me 5 minutes installing without hand guard removal tool and the allen screws lined up perfectly."

"Went on really easy. Did not find any problems with installation. When I shot the rifle I found this rail moves side to side about 1/4 inch in either direction. Makes the gun totally inaccurate."

"Well built quad rail fit tight without set screw. With the set screws in place it will not move. Have run 200 rounds with it in and it did not back off. If you want to get a flat top look with keeping the delta ring get one. I did add a flat top gas block to finish off the look."

"The quad rail arrived in three days. I put it on by hand, but you will need a #2 hex key to tighten the 4 screws. It fit my DPMS A4 upper with no problem. It is a tight fit with no movement. The quad rail lined up great with the rail of the flat top barrel. I am glad I did not spend $100's on another quad rail."

"Ok, was looking to keep the delta ring and after buying my optics was short on money. I read the reviews that were existing and decided to try it. Man, I don't like buying Chinese things but for the $, this was the nice surprise. locked in tight as could be and has held for several hundred round thus far. DPMS Orbital. Rail matched perfect and will suffice till I free float."

"I've been looking for a good deal on a quad rail. I found it. Pros: This rail has the extended top rail for that \"monolithic\" look, installs like a standard carbine hand guard, has four set screws that lock to the barrel nut, white \"t\" marks and does not weigh down your rifle. Cons: finish is not \"milspec anodized\" it's more like the \"Teflon\" style and there are slight tool marks in the rail notches. I highly recommend this rail for anyone on a budget. Perfect for a camo job! Pull the trigger on this one guys."

"This quad rail drop in was easy to install and is an attractive economic alternative to the MCTAR-17P that I had been thinking I needed to replace the junk handguard that came on my DPMS Sportical. The SureFire Ladder Rail Cover 7\" 3 Pack Picatinny Black Z70 work very nicely on this but fall one rail short of complete coverage..not a biggie, you can cut the third cover to fill the gaps if you want. One other thing, the rail gas block on the Sportical is lower plane than the rail on the upper receiver..so buy the right Front flip up sight for a rail gas block to be sure it lines up with your chosen back sight."

"I am matching this side by side with my $155 MI Quad Rail. MI paints the numbers on the even slots, and this one has them on the odd slots. End of difference. There is not $100 worth of difference.The only thing and it is very minor is that Gun Tec uses Allen screws to locate the quad rail rather than molded in detents.I would install, make sure that the rail is aligned with the upper and the red loctite those screws."

"Awesome quad rail. I put this on my DPMS and it fits perfect. I added the smallest of dabs of locktite to the set screws to be sure they stay set. They're small and they do firm up the positioning. Makes a flawless transition to the flattop upper and just gives you so many mounting options without breaking the bank."

"The extended rail on top was the selling point, then the price. Why put a $300 quadrail on there when you can spend $50 and get the same result. The item looks great, the set screws hold it in tight and easy to install."

"Overall, the fit and finish is very nice. This unit is made in China, which was not made clear in the description."
