I'm trying to get more info on the MI #20 also. Weight and install. Can't seem to find any good pics of it mounted. Does the cap on the front sight block need to be removed for it to "free float". I also have a 14.5 with perm attached FH.

Any of the rails will fit on it. Some will require more work than others.
Can you be more specific. What are you looking for? |

It has a 16 inch barrel, looking to put a light and/or bipod on it and a scope in the future. Id prefer to get the 4 rail system so I dont have to change it later to add more stuff onto the rifle. Let me know if there is any other info that might help you in helping me

Do you want or need free floating?
Do you have a budget (money) in mind? Do you have a budget (weight) in mind? Are you going to do it yourself, or have someone else do it? Do you need/want a certain length? Most carbines use a 7" handguard, but some of us have run longer (up to 13") handguards and used a low profile gas block instead of the FSB. |

FF means that weight of the accessories doesn't effect the point of impact. It will have a side benefit of making the carbine more consistant. Most people don't need all this, but it's nice.
A couple of options for you to think about. Non-FF rails like the YHM($120), MI($140), and Samson ($200) just replace the handguards and offer 4 rails. The YHM is the lightest, with Sampson being a close 2nd - the MI is the heaviest. These will do the job for 99% of most folks. Think of them as a cheaper alternative to the KAC RAS. FF Rails like the Troy MRF-C or Samson MRFS-C are easily installed. All you have to do is remove the delta ring assembly (a dremel tool w/ cutting wheel and 15 minutes is all you need) them the unit clamps onto the barrel nut. These weight a bit more than the LaRue/DD/KAC systems but don't require removal of the front sight base (with is a PITA) nor do they require removal of the barrel (which requires more tools). There is also the ARMS SIR a FF system that just drops in and has an attachment rail that covers your flattop. Easiest to install, the 'C' model doesn't even need removal of the delta ring assembly. Downside is it's one of the most expensive and heaviest of the rail systems. It also raises the height of the flattop rail and limits your choice of back-up-iron-sight. You cannot use a detachable handle with this unit. For your budget, I'd suggest either the Samson non-FF if you want simple, or for $50 +/-$10 more get the Troy MFR-C or Samson MFRS-C FF if you think you want the benefits of free-float. |

I have not tried the LaRue or Daniel Defense, but I did just get the Samson MRFS-C (Carbine, 2-piece FFHG, quad-rail). The installation was uneventful, I used a DCH to align the top rail and torqued the bolts to 3 ft-lb. The barrel clamp basically clamps to the barrel nut much like scope rings with a scope tube. I've tried twisting it to no avail. There are 2 "wings" that help locate the top rail with the upper receiver just in case the barrel clamp fails. The lower handguard slides into place with tabs and a detent. It added about 0.25 lb to my carbine which isn't that big of a deal, but the rail covers haven't gone on yet (still waiting for them) and that should add a bit more. IMHO, I was looking for a lightweight carbine build and in retrospect, a little more weight is probably better. With a 7 lb build, my M4 was kicking a bit hard (enough to sort of bruise my face due to the tight nose-to-CH cheek weld I had) whereas my 12 lb 24" HBAR was shooting as soft as the PS90. LaRue is coming out with the AR-10 style locking system, which is what you should wait for (or was it daniel defense?) but both the DD and LaRue require removal of the FSB, whereas the Samson / Troy / MI 2-piece FFHGs simply snap over the stock barrel nut. I chose to remove the barrel rather than cut the delta pack. I had to check the barrel index pin anyhow. |

I was about to purchase th YHM forend for around $100 for my Bushy M4 with 14.5 inch barrel and perm flash sup. Then I read this thread and learned i can do free float myself with the Troy MRF-C or Samson MRFS-C. The only items i will have on the rail are a pentaon UL200 light, VFG, and a sling. I'm not sure if I need FF, but I am wondering what the best deal I can get on one of these are. Thanks in advance.

Quick question, does anybody know if the current version of the Troy MRF-C still has those funny looking grouves that run down the length of the float tube?
I always assumed they were there to act as "heatsinks". But I think they look a bit odd. |

Please understands that it is indeed "interrupted" as it is seperate from the receiver. It is not the same as a MRP or the Vltor VIS monolithic upper receivers.The receiver is made at one factory, and the rail is made in a completely different factory, and is sure to have different dimensions. The Troy, Samson, and the new DD Lite rails only offer the "look" of an uninterrupted rail, but the area where the receivers rail and the handguards rail meet should not be used as a mounting surface for optics. You can either mount your optic on the receiver or mount it on the handguard not on both at the same time. |

[#35]
Just wanted to clarify this as many have gotten the idea that it is indeed "uninterrupted", and go on to mount their optic mounts half on the receiver rail and half on the handguards rail. Since the only real benefit of the "Uninterrupted look" is that it "looks" cool, it should be addressed as such. |

So what's the best lightweight 4-rail free-float carbine-length handguard for the money?
The Daniel Defense 7.0 looks good at $245 (Denny's) and 8.5 ounces. Is there anything almost as good/light for less money? The Troy Industries MRF-C is $209 (Denny's), but it's 11.5 ounces. The rest of the carbine it's going on will be high-end, so we want a quality handguard, but the barrel already be on the heavy side, so we don't want a handguard that weighs a ton. |

I like the concept of the customizable handguards like YHM has. Does anyone have experience with them?
They make the FF and regular two-piece models. Does any other manufacturer make a customizable handguard such as the YHM? For a RRA carbine, how much accuracy do I gain from FF?? I suspect not much. |

Lots of manufactureres make FF handguards with moveable and/or removable rails of different lengths. Badger and PRI spring immediately to mind, but I know there are others. It also isn't too difficult to glue and/or screw rail sections onto a CF or Aluminum FF tube exactly where you want them.

Are your YHM the old kind or the new ones? The new ones have anti-rot screws and cannot turn once properly installed. Anything but the older YHMs should work fine for you. |

Actually, I got the ass and I am taking the YHM setup to the gunsmith tomorrow so he can remove it and go back to the stock handguards. I found a set of MCTAR-17 (2 Piece Carbine Length) from MI for 129.00 shipped. That will just snap into the place of the original handguards. I was not planning to mount optics anyway. I read a good review of the MI handguards. |
