How well do the railed handgaurds on the A4's hold their zero when mounting optics or laser's on them?
I know the A2 hangaurds are unreliable.
also how reliable are the railed hangaurds compared to free float barrel systems

Wouldn't this be a function of fit and mounting of the individual handguards? For example, the Magpul MOE handguards I bought had significant slack in them after mounting, but the rails mounted in the same position are rock solid. I'd expect FF rails to be much more stable than non-FF.

Your right this would come down to the type and fit of each indivdual handguard/rail system. But unless if your using an IR lasering system I wouldn't bother using a laser, thats like screaming HERE I AM to your enemy.

BUT back to the question. Your most stable solution would be an FF forend or a monolithic rail/flattop receiver.

the standard gi issue knight's armament rail systems are more than rock solid enough to retain zero -the thousands in use in the middle east and central asia seem to be doing the job pretty well

I knew the KAC ones were very good what about YHM

I obviously know that freefrloat is the best i want to know how well the two pieces hold zero.

buy a quality rail and movement wont be a problem. I have a Troy DI rail that is rock solid. I just ordered a M-4 RAS so I can't comment, but they have great reviews as well.

Don't get into the FF vs non FF thing. You wouldn't be able to notice any accuracy difference anyway. This is what I have found with my own rifles, YMMV.

This is true.

Also a red laser shouldn't be your main method of aiming no matter what.

People do and have mounted Aimpoints and EoTechs to KAC M4 and M5 RASs. A solid FF rail would definitely be a better choice for this application though.

i am looking for a mounting platform for an aiming device on the handgaurd that will maintain zero. i understand that a laser should not therefore is not the primary aiming device. the question is what is a good cheap option for a railed handgaurd that will maintain zero

just want the laser to supplement optic

I agree. Mine have performed really well with my limited experience at the basic school. they definitely get abused here, and my zero is still good.
