My go-to now is the Aero Precision M4E1 series. But if you've got small hands you may not like the girth of the rail. I personally like them because they fit my hands well and if I wanted to stuff my F1 cans under the rail they'll fit.

Fortis/Rainier Switch the barrel nut does not need to be timed. They have M-Lok & KeyMod.

SLR provides an enormous variety of styles and lengths. Can't go wrong with SLR if you can afford them.

These are the ones I have installed.

You can add REV arms to the list. Lightweight, no indexing on the barrel nut.
Used one on a build last year, very nice. |

I love midwest industries and have the Gen 2 with are easy to index. But their Gen 3 do not require and indexing so that would be my suggestion to you.

A pleasure to be mentioned. Let us know if we can assist in any way!

Cross Machine Tool. I believe the Seekins NOXs rail also. Not 100% sure about the Seekins but I will know tonight when I install it on the upper I'm building.

Timing is not that big a deal. Pick a hand guard you like, lube the barrel nut, start with a torque wrench at 30lbs and then tighten with a breaker bar to get it timed right.

Daniel Defense. Not sure of the others, but definitely lite rails.

I am doing this exact same thing with two integrally suppressed rifles. 1.5" OD suppressor tubes fit well underneath the rails and no timing issues.I have gorilla hands so rail size is perfect for my hands although I do like how slim the BCM rails are. |

Midwest Industries Gen3. Got one of these on my rifle and it was easy.

The Seekins NOXS does not require timing. It does however require a special crow foot wrench that hard to find.

The MI Gen 3 is a nice rail and requires no indexing. View Quote ^^ agree. MI gen 3 is my preferred for ease of assembly/anti rotation feature/and value. The barrel nut is harder to deform versus the BCM KMR & aKMR, and it's much easier to get the rail seated/unseated on the nut by using a plastic pic/etc to slightly wedge between the ears of the loosened clamp, making alignment of picatinny rails extremely easy. |
|
Its pretty much down to the MI Gen3 Mlok rail or the Faxon Rail, I just found a nicely priced MI rail and may just pull the trigger on it. I'll post some pics when I am getting it together! Thank again everyone for the suggestions!

I'd suggest looking at the ALG Defense (Geissele subsidiary) EMR (Ergonomic Modular Rail) line.
https://algdefense.com/rails/an-introduction-to-our-ergonomic-modular-rails.html The barrel nut installation is both bullet- and fool-proof, guaranteeing proper torque without the need for a torque wrench and automatically aligning the nut for the gas tube to pass through. The nut is long with a close fit, providing a robust rail mounting. And to top it off, they are not outrageously priced. My last three builds have used EMR-3's (I have one recent build in which I recycled a Troy Alpha Rail, otherwise I would have purchase another EMR). |

If those aren't enough choices... you can pick up a lapping tool to square the receiver and then you can time any hand guard you want. Not hard with the right tool.

The original modular float rail 9 and 12. Like this: http://www.ar15news.com/wp-content/uploads/2011/04/daniel-defense-mfr-12-2.jpg View Quote Still my favorite. Many of DD's rails use nuts that don't have the gas tube pass through, and are not indexed. |

I like the UTG Pro handguards. I have the keymod version and I'm impressed. Quality is great and its US made. They only work on standard upper receivers though.

View Quote Now, with the advent of free float handguards that have a very tight grip on the barrel nut, no need for interference with the gas tube. In other words indexing and/or shims for FF handguards are an obsolete leftover, the sooner they are eliminated the better, IMO. Cost aside, I consider BCM's KMR line to be the very best, with SLR's Solo line a close second. The titanium barrel nut for my SLR ultralight handguard tightens with a simple 1-1/4" crescent wrench. - CW |

+2 for Diamondhead! VRS-T is the most comfortable handguard I have . Very easy assembly too.

Correct me if I am wrong, but I am seeing pictures of handguards that have screws that go through the rail and thread into the barrel nut.
So even if you don't have to index around the gas tube, you still have to torque, un torque, shim, retorque.... etc.. to get the top of the handguard to line up with the receiver. Some designs, Armalite for sure, and I think the Geissele and BCM KMR, do not require you to do anything with the barrel nut but torque it to the proper spec. There are anti-rotation tabs on the handguard, but it clamps down so snug that it can't move. |

I am loving the Strike Industries Mega Fins rails. They have a really good barrel nut design. Its a nut inside a nut and allows you to align the outer nuts gas tube port and then tighten the inner nut.
Good luck! |

I have the Faxon Streamline and it does not need to be timed. Very solid and well built for the cost. Faxon produces good stuff.
