"Excellent handguard for the price! YHM products are well known for quality & price, plus the CTD price was even better! Installed on an AR pistol with a 7 1/2\" barrel, covers the entire barrel just past the threaded tip (install your flash hider first) Any two pin free float tube wrench works, YHM doesn't require torquing of the barrel nut, and if you center the gas tube opening correctly, the handguard levels itself out via the anti-rotation screws. Couldn't ask for a better product!"

"I been serching for a very good free float hand guard, but not too expensive. And I just found it. I put over 300 rounds 3 day after I got it, and the barrel stayed cool, and also made my Stag Arms AR-15 look sick at the range. Yhm are great. Thank you CTD."

"I was building an AR upper and wanted a free float rail system so I did some review research on the various types. This system replaces all the normal parts, barrel nut ect, that normally would be used to attach the barrel to the upper. This removes some cost and complexity to the original system. The YHM easily attaches the barrel but uses the YHM three prong wrench to tighten the system down. I actually made my wrench with some cut down 16 pennny nails and soft steel scrap with my welder, but I do recommend buying the wrench for normal people: Makes things alot easier and quicker. The quality is extremely high and the system is quick to install when purchased with the YHM Free Float Wrench. I also added a YHM Endcap which really set the entire rail system off will a professional appearence. Unlike other more expensive systems, the YHM Diamond Series has this unique End Cap Option, it also has the upper rail alignment that offers a monolithic appearence. I was so impressed with the quality and thoughtful design that I added the YHM QDS Flip Up sights. These are very compact and sleek sights of all metal construction. Previouly I was going to go with the Magpul MBUS Flip Up Sight System, but the YHM Quality had sold me and I steped up to the plate for superior quality. Having drifted a bit in this review, I would add that I found features which are superior to other systems and that the quality and value are the best available with current technology. I highly recommend this system on these accounts."

"I just put this handguard on my DPMS. It fit great and went on flawlessly. It matched up perfect with my upper rail, fit tight, and fellt secure. I installed a Troy TRX 7 inch on my M&P 15 at the same time, and found the Yankee Hill to be just as good for a lower price thanks to CTD! The Yankee hill wrench works well for installation. I plan on buying another for another build or maybe two more! This is a great product from Yankee Hill Machine and priced right thanks to CTD."

"This YHM Diamond Quad Rail is the nicest looking best performing quad rail that I've ever had.....ok it was the first I ever had but it is working great on my Stag Model 3 and looks great. Highly recommend!"

"This is a very nice piece of kit! It is everything that I was expecting.. now with that said, I used this on a 7 inch pistol project in 5.56mm it added just the right amount of weight that I wanted and the mounting options as well! It fit perfectly on the upper that I used and locks down very tightly. One thing I noticed in one of the postings that u don't have to tighten this down as per mil-spec. Yes you do, the barrel nut must be torqued down to 30 foot pounds or it WILL come loose! It's the barrel nut! It will not come off do to the gas tube being there, but you don't want it to come loose either, explosives in close proximity to your face!? Anyway, you will not be unhappy with this fore end!"

"I got this carbine length quad rail for my RRA AR-Pistol. It was an easy install. No fuss putting it on and it looks great. It's pretty light weight for the quality and strength. And a great deal for the price. I would recommend this to anyone thinking of upgrading to a quad rail. (keep in mind, if you get this you WILL need to use the tool and disassemble the entire foregrip. It is NOT a slip on.) That being said it was still a very smooth install."

"I put one of these on my bushmaster AR-15 and I love it so far. I didn't give it 5 stars because I don't have anything to compare it to. This is the first one I bought after a friend told me that Yankee Hill makes great products and is not overpriced like some of the other companies. I do recommend getting the rail cap that sits in front of your gas block also it just makes it look that much nicer. Very pleased with CTD as always best prices and service."
