I'm just curious why there are no free float handguard torture tests? I'm sure most of them bend fairly easily but would be nice to know that ones that are stronger than others...

The rails being used in combat would be a good place to start?  They seem to be holding up well.

The Daniel Defense RIS II rail is a battle proven rail.

Larry Vickers beat the tar out of a BCM KMR in a video and then shot it, does that count?

I know non free float hg do well, I'm not looking for a shtf free float I just thought it would be a good thing to do to see what ones bend really easy as opposed to higher end durable ones

like what a free float would do if dropped from 5-10 feet.... etc.... ooh,, also maybe what temps they get to after firing x amount of rounds etc

Post vid?

do a search youtube search for Daniel Defense torture test, all of their rails are free floated.

good info, keep it coming..

Haha Intacto just for funsies

no it isn't.  what rail is it?  Is this supposed to be a KMR thread now?

Probably because they'd fail.

To my knowledge, there is only one design of free-float handguard currently being purchased in quantity by the US military, and it is a chunky beast compared to the slim and sexy rails released in the last few years.

I'd love one of the newer rails, but after reading long-term durability threads, watching vids like the above, and asking a similar question in regards to maintaining zero on a handguard mounted front BUIS, I've come to the sad conclusion that a lot (maybe even all) of the high-end light & sexy rails being sold still aren't ready for prime time. Granted, I've purchased items that I knew ahead of time might not be fully idiot proof, but it seems to me that we're putting a lot of eggs in one basket when it comes to extended FF rails, and I'm skeptical that many of them are really up to the job.

BUT I WOULD LOVE TO BE PROVEN WRONG.

What I'd personally like to see is a torture test where an extended FF setup is repeatedly dropped (5 or so minimum) onto a concrete driveway from multiple directions without significantly shifting the front BUIS zero as compared to a non-free float.

Give me that in a slim, light & sexy package, and you got my money. Give me that in a detachable format and I'll buy two.

The Army tested 7 in 2010.

Simple test.  Ask them all to donate one rail to prove how tough it is compared to every other one.  Those few that are actually confident enough to give you one are the winners.  



No.  You just happened to post "here you go" right after someone said that they wanted to see one on a KMR.  Just bad timing.

There was a guy on M4forums (IIRC) that did some testing on barrel deflection after hanging a steady increasingly amount of weight was attached to the rail.
It was very informative, you may, or may not, be surprised at some who refused to donate one of their rails for the test.

I wasn't.
