good but...

the rail is good, very lightweight seems to be durable construction but I have a few gripes.
<br>you need a skinny crows foot socket to install good luck finding one... lowes, autozone/advanced auto, tractor supply, harborfreight, ace hardware, and a few others didnt have one that big, and I suspect if they did it would be too wide.
<br>Include a cheap chineseium crows foot socket so someone can properly torque down the barrel nut.
<br>Also the barrel nut only has threads on one side so hopefully you can get it to line up with the single included shim.

OK for the $ but engineering was lazy

Rail seems to function fine but ID was just a little too small to comfortably space itself over an adjustable gas block. The barrel nut, as others have mentioned, requires a narrow wrench which is stupid. The flat spots could have been widened to prevent marring. Finally, if shimming is required to properly align the mounting screw locations, why couldn't they slot the mounting screw holes on the HG? That way you're ensured minimal gap between the upper receiver rail and the HG rail.

Being an AZ guy I wanted to like this rail. Sadly, spent another $40-60 and get quality. It requires a crow foot wrench that you need to order from Guntec at an additional $20 plus shipping. If you somehow mount the barrel nut without their tool the aluminum barrel nut will be marred up. It is virtually impossible to install so that the receiver and hand guard top rail align. The UTG has a better system if you watch their video. I will leave this Guntec junk on until I can get another Troy rail that I should have bought in the first place. Primary Arms is still the best in the business.

Almost Awesome...but not quite.


Very lightweight, solid, good looking handguard. My only criticisms are: 1) A tad more work to install, because the barrel nut has to be timed in order to install the handguard with the top rail at exactly 12 o'clock. I wish it was clamp or friction style. 2) It has an aluminum barrel nut, which is okay if your intention is to keep your build as light as possible, but I prefer a steel barrel nut. 3) Doesn't come with a barrel nut wrench. For the money, this is an outstanding handguard.

1 year of religious shooting and still looking sharp.

Wow, it’s been a solid year and it’s a good upper. A little heavy than advertise but prestine look on the AR. It literally requires 6 star/torq screws to hold it in place. Set it with locktite and your golden. Make sure the barrel nut is torque to spec/ft lbs. Not bad for price and it’s quality.10/10 would recommend.
