I'm sure I'm not alone when I say that I need a quick and dirty guide to ARMS, KAC and anybody elses rail systems. What's available, what features do they have, who stocks what, etc. The web is woefully behind in this area and a bleeding edge site like ARFcom should be the place to look. Maybe a tacked thread with specs or the like.

It would certainly help those of us out here trying to determine what rail system to choose!

uuhhmmm....did you read the thread tacked at the top of this forum?

Yeaaaaahh, I did, when it was fresh a couple of months ago. It didn't tell me thing one about the status of new mounts that are constantly being referenced around here. Lots of talk but no pictures or much regarding their utility. Just thinking it would be nice to have a thread ala the AR Comparison chart for us discerning shoppers!

How about listing weight as well?

Wow, TheRicker, you get the Serendipity Award of the Month! This is [b]exactly[/b] what I was looking for. Well, weights [i]would[/i] be nice [:D].

Ricker, Nice Graph, 1. don't forget that the 45's aren't true uninterrupted rails, they detach/flip for the dedicated PEQ-2 mount. 2. For the less informed, you might want to change: "cut off delta ring" to Cutoff/remove" just so they know it's not a permanent/irreversible change. 3. And, the 58's a bi-level. Nice job, though, SUL2

[b]TheRicker[/b] - EXCELLENT work on that chart, and I vote to tack it up! Some suggestions on the #45's: 1) put [i]"level"[/i] for the [b]Top Rail[/b] description, then [i]"PEQ Top Mount"[/i] under [b]Other Feat.[/b]; 2) put [i]"PEQ Optional"[/i] for the [b]Top Rail[/b] description. Great job! .... Chris

Very nice chart! How about a colum that might say rail choices, or selective rails, to show there is a choice, at least on the SIR. Heat shilds on the SIR I would classify as not needed/ NA, because of the way it has a dif. way to handle heat by it's handguard. Good shootin, Jack

Are you going to add PRI and Daniel Defense? Also if you ever are able to get the weights be sure it is weight vs original set up. For example the SIR M is weight of unit minus Delta ring. The FF RAS is weight of unit minus Delta ring and barrel nut, etc.

Ricker - excellent job. I added a little bit from a blurb I am working on... Knights Armament Company (KAC) Free Float RAS -no traditional under barrel attachment can be attached, allows for unimpeded mounting of (most) optics, light and or lasers. The barrel nut can affect some optic positioning. KAC M1913 Rail Specifications allow for M1913 Accessories to be mounted and retained with ease. KAC URX 4x4 - Mounts M203 or KAC AGL system via locking rails allows for freefloat of entire system. Due to the unbroken top rail it allows for unimpeded mounting of optics, light and or lasers.

TheRicker, one note, the new versions of the PRI tube do have heat sheilds. Don know if you knew that. Excellent chart.
Link Posted: 6/1/2003 9:00:48 PM EDT
I am pretty sure The lower portion of the handguard on RASII has a heat shield. Your chart is excellent! Great for everyone!
Link Posted: 6/2/2003 8:06:11 AM EDT
I thinking it would also be nice if the weight of each unit was listed. Even without it it's still an awesome chart! [:D]
Link Posted: 6/2/2003 10:26:33 AM EDT
Ricker, Any help I can offer I would be glad to do... I am still so far behind on the SIR (many variant), RIS/RAS/RASII/FFAS/URX, FIRSH, etc/ rail test. Some of the guys took stuff we were going to tes overseas...

TheRicker, The RASII has a heat shield on the lower panel like the RIS and RAS. Wes and PaulE are the best for weighing the items, as they tend to have several disassembled units available. I have nothing apart right now - of the stuff I have lying around.
