AR-15 QUAD RAIL SYSTEM
Here at NcSTAR, We are continuously expanding our line of AR-15 Accessories. The request for an NcSTAR multi-rail handguard set has been so overwhelming that we couldnt hold back any longer.
Introducing the AR-15 Quad Rail System. This 4 Rail Handguard System is designed to replace your standard AR-15 handguards installing in minutes with NO gunsmithing or modifications required.
The Removable Weaver Style Rails are Customizable so you can attach Forward Grips, Flashlights, Lasers, or any other type of rail mounted accessories.
The Quad Rail System is constructed of Hard Anodized Aluminum to prevent corrosion for lasting durability.
Choose from Carbine Length MAR4S (6.5 inches) or Rifle Length MAR4L (12 inches).

Having a lot of trouble installing it on the Ruger AR556. Any tips?
Will this for the Ruger AR 556? Also, since it's aluminum, how will it handle the heat?
What are the 2 empty screw holes on top
did he not put the front end under the cap? it looks like he just put it over the cap and tightened down?
were can i get the generation 3 i cant find it anywhere
Will this fit on the Ruger AR 556?
yes it is a 10 and a half inch barrel carbine light gas system has a little bit of play back and forth
installed the quad rail has a little bit of play in it is that normal
What barrel diameter is this handguard compatible with?
My airsoft m4 has a 14 inch outer barrel. Will it fit?
I have a question. Will it fit an 14 inch airsoft m4 carbine?
That Quad rail looks heavy and kinda large. What does it weigh?
hello friends,I'm think input a handguard like you,but i´m not sure if my battery keep inside handguard .my gun is a G&G COMO 16M M4A1,thank you.
so it just fits into the holes on the handguard on ur gun like…. I have a jg m16a4 and there are no rails just a standard handguard with holes
so it just fits onto the handguard on ur gun like I have a jg m16a4
Your lighting was kinda bad. I was thinking about getting this, but it looks weird in the video.
OMG thank you for this video! I got the system in a clear package with no label and no instructions. I was watching all kinds of video trying to figure out what to do, I almost cut off the delta ring. I simply had it backwards 🙂
can this apply to gas airsoft guns?
@therealrrc It's a standard quad rail, a non-free float. It uses the front handguard cap & delta ring to secure it to the firearm.
free floating or regular?
@501Biteityouscum The NcSTAR Quad Rail fit Over the front handguard cap and Not Inside like the standard GI handguards. The back of the NcSTAR quad Rail fit over the Barrel Nut and Inside the Delta Ring just like standard GI handguards.
@tinytimisabeast00010 The rails on the MAR4S (Carbine length) = ~6½"
@dsfasfasfasfasf See my previous replies to comments below about fitment onto various Airsoft guns. We only have access to real steel firearms, for which our products are designed/made for.
will it work on the KWA M4A1
@Airs0ftProducti0ns it fits onto an gun with a delta ring, but you might have to pick up a battery box
@NcSTARInc ok thanks
@Airs0ftProducti0ns the quad rail was made for real steel AR-15 carbine/ M4. It would depend on how close your G&G M4A1 is to a Mil-Spec M4. It would also depend on what you have under the handguards, some airsoft guns store the battery in that location. The battery may interfere with installation of the NcSTAR Quad Rail.
@speedyj305 the quad rail was made for real steel AR-15 carbine/ M4. It would depend on how close your Tippmann M16 is to a Mil-Spec M4/M16.
hey would this work for a g&g m4a1 carbine
can it work on a tippmann m16
@Popsicle22754
UPDATE: Both NcSTAR Quad Rail models are now made lighter with the current production models.
Carbine length = 11.1 oz.
Rifle Length = 19.5 oz.
Each of the four Picatinny rails are removable. The rails slide onto dovetails machined into the handguard body and are secured by Allen bolts to the main body. The individual rails can be removed to make them even lighter.
@PlayerX5900
This was made for Real Steel AR-15/ M4 carbines. We do not have a "dboys m4 3181" or any other Airsoft gun to test fit this onto. It would depend if the Airsoft gun manufacturer made it to M4 Military Specs or not. It would also depend on what you have under the handguards, some airsoft guns store the battery in that location. The battery may interfere with installation of the NcSTAR Quad Rail.
@gulfport69
It's not designed for a Keltec Sub 2000. It's a drop in fit for AR15 carbine and we also have have a quad rail for AR15 rifle length rifles that use the GI handguard.
@andersen8183 – the quad rail was made for real steel AR-15 carbine/ M4. It would depend on how close your airsoft (dboys m4 3181) gun is to a Mil-Spec M4.
does this work for a dboys m4 3181? Please respond!
