ohhunt Tactical Free Float Quad Rail Handguard With Barrel Nut 4" 7" 10" 12" 15" Installs On Standard Carbine .223 5.56 AR15 M16 Rifles

I have 10 builds (still in progress). At the time of this review I have all the ohhunt barrel nuts installed and 4 of the handguards. The price for these rails is outstanding. Trying to keep the investment as small as possible (when sold, new owners will customize every part to their favor). I think they may just keep these, unless very particular. I had inadvertently bought barrels with dedicated pinned low pro gas blocks, making free float a necessity. Finding these was an unexpected surprise. Only thing is there is no instruction - though I watched an identical handguard install online (same mfr I presume). The ONLY thing I found was a slight variance in the HEIGHT of the gas tube holes when torquing (the gas tube would tap the receiver entrance on the top side (I have a cheap flex video scope). But the tubes all passed through and everything seats fine. I am very pleased. Mid $300's for 10 free float handguards.
Bear in mind these are set up to receive the rail end caps. If you want them, ohhunts makes and sells them too. They attach to the open end of the rail with 4 tapered screws (to prevent things from getting into the handguard area - if you desire), and the caps have 2 small set screw against the barrel. THESE MUST BE INSTALLED BEFORE THE MUZZLE. So I thought to mention that (I have to remove 4 crush washers - my poor planning).
You will need a strap wrench (cloth one is best). I got mine at O-reilly's.
- Install barrel nut/gas block&tube according to standard rules
- Remove the handguard set screw at the bottom rear rail.
- Handguard screws on to barrel nut (lots of threads). I used 1 drop blue loctite on handguard threads.
- Screw the handguard lock ring (threaded outside the bbl nut) full rearward toward the upper receiver to keep out of the way during HG install.
- Do not thread HG against upper receiver, even if it fits perfect. I found out you'll have problems with tolerances around your takedown pin space. Back off to the next alignment. There will be a small gap (mm+) between HG and upper continuous rail. (Big deal, IMO).
- This is where you use your 'estimation'. Play around backing off the HG about another 30 degrees further from rail alignment, then tighten the lock ring forward against the HG snug. That 30 degrees (or so) will now be retightened against the lockring with the strap wrench. You can keep backing off, retightening the lock ring easily until you're happy with the amount it takes to tighten to rail alignment.
- Wrap the wrench strap around the HG rail that surrounds the barrel nut (this will minimize stress). Now tighten with the strap wrench that 30 (or so) degrees until your rails are aligned. It doesn't have be super tight, but good and snug.
- Re-install rail set screw (I used some blue loctite) on bottom rear rail. You'll notice that with the top rails (receiver and HG) aligned, the design of the barrel nut slots mates with the set screw which seats secure into one of the valleys. I tightened this pretty tight.
-For grins, I took a punch and LIGHTLY angle punched the slot on the lock ring (on one of those slightly raised edges) clockwise (looking toward muzzle) to assure tightness.
- Install handguard cap (if desired) and muzzle.
I am very content with the sense of firmness and security of the handguard. The 'screw on' method seems very secure, there is a LOT of threading on the bbl nut.

I have no review to give. Still waiting for the product that I ordered to even ship from Chicago. I bought this thinking that I was getting a deal, but I'm starting to think I should have paid more to get a useable product sooner. Not sure if I'll be ordering anything else. Wish I could leave a better review, but they emailed me and asked, so here it is

Great products and great price
