Type of Railed Handguard on Benning's M4's

Does anybody know what type of handguard is being used on the BRM M4’s at ft Benning?

I can make out every part I’m trying to identify except that. Looks like some sort of 2 piece quad rail, but can’t be sure.

I’m looking for a set.

From many of the pictures I have seen of the Army’s M4s, they are most likely using the KAC M4 RAS.

They’re all KAC… across the Army … and yes 2 piece

Hmmmm… Never thought of that one…

YES!!!

Dude you nailed it first try!

Going to convert a spare M4 I have to a close copy of what they are using at Benning, and give it to one of my sons as a primer for what he will be using at Basic, Jump School, and maybe Ranger School?

Thanks for the help!

You can get “seconds” right from KAC. I’ve ordered a couple sets in the past & the blems were pretty minor. Well worth the $100 savings.

Outstanding thanks.

I’m assuming the MaTech BUIS is the most likely rear sight in use.

Ill be listing a few for sale in about a month after I order my new handguards if youre in no rush and dont mind a little krylon.

Man you just saved me $100!!!

This will be a beater/training tool for a year, and then handed over to the young man as soon as possible.

You never know… I’ve got more AR projects going then I can stay on top of, it may take a month, I’ll keep a look out for it, or give me a heads up.

Krylon is my friend. Thanks.

It is true that all non-SOCOM M4s are still using the RAS, but not all are manufactured by Knights.

My issue M4 ( and almost all of the M4s in our armory) has a rail made by P&S Products.

It’s identical to the KAC ones with the exception to the barrel but clamp screw on the top rail. These have a flat head vs. allen head on the KAC.

The nice part is that although it’s well documented that the Army bought a run of the P&S manufactured rails… No one seems to realize they’re not Chinese airsoft clones.

I picked one up NIB for $40 on fleabay for my last clone build. Last KAC RAS I picked up was like $120 used.

Will no doubt shop around for these parts as this will not be a ‘presentation piece’.

I played with one of the Colt M4 A1’s yesterday, and the temptation was to just pay $1,300 and walk out with the finished product, but it’s not like I don’t have a suitable payed for AR already in the safe not getting used.

The rail has slotted screws, and is marked Modular Rail Forend M4 Carbine, and L/N NH-40030. I assume this is the P&S forend. Was VERY well made.

Early KAC RAS clamp screws used an allen head screw, but newer rails all use the flat head screws. This revision was done to facilitate re-tightening of the screw in the field without the need for an allen wrench.

That makes good sense, then perhaps the civilian Colt M4A1 is using an actual Knights?

Mine is

Some civilian Colt LE6920 SOCOMs use Troy drop-in rails.

He’ll have either an FN or Colt M4 on Sand Hill with a KAC rail, the closest thing he’ll touch to a weapon is a 2x4 in Jump School, and he’ll shoot a shitload of blanks from either an M4/249/240 in Ranger School.

Best of luck to him. If he’s an 11B and winds up with orders to the 82nd, shoot me a PM.
