CAA’s NEW M4S1 M16/AR15 carbine handguard sets the standard for a stable and rigid design by combining interlocking top and bottom handguard sections with a bottom rail that can be mounted to the existing sling swivel mount for additional rigidity. M4S1 handguard will not move once locked in place providing repeatable zero.
This is the first lightweight polymer handguard designed to withstand the extreme operating temperatures of a gas piston system. This extreme heat resistance is achieved by manufacturing the M4S1 from a proprietary heat resistant polymer, including heat shields and providing significant upper and lower handguard venting in the design. The M4S1 also works with standard direct gas operating systems.
The M4S1 includes two interchangeable lower rails of 4” & 1.75” lengths. The this allows the operator to quickly change rails based on mission need. The two 1.75” side rails are removable if not required. Even with the side rails attached there is enough room left on the contoured handguard for your hand to hold it comfortably. An optional 9” long aluminum top rail attaches to the handguard and flat top rail providing a super stable platform for mounting optics and sights.
The M4S1 also includes 2 mounting points for a push button quick detach sling swivel. Interlocking top and bottom handguard sections with a bottom rail that can be mounted to the existing sling swivel mount for additional rigidity.
Thanks for sharing. Always good to find a real expert.
Now if they just had one in Mid-Length format. I know allot of folks that would like another option for a polymer fore-end and not pay big bucks for a machined one. Especially if its “repeatable-zero”, and offers what this one has. sign me up.
When is the 9″ aluminum top rail going to be available for the M4S1?
We are waiting for a shipment from Israel. Should be about 30 days possibly longer.
I will pass this along to our development team… Thank you
hi to all http://www.commandarms.comers this is my first post and thought i would say hello to you all –

I love the way the Israelis engineer solid, lasting goods in every aspect of life.
Truly a blessed People!
I think this will soon be added to my M4!
Yes, we people of Israel are blessed. Best to stay on our GOOD side!
Back on topic: Doesn’t look like this foreend free-floats the barrel, correct? Do you have any photos with the cap/side-rails off?
Need rifle length, fast!!!!
not sure what you are asking for?
