Free Floating Quad Rail, Info Needed.

[Earl33]

I would like to put one on my AR. It's a Bushmaster Carbine w/ piston. Seems like all the manufacturers state that their Free Float Rails may or may not fit some Piston configurations. I don't want to spend time fighting a losing battle on this little project. Anyone use a similar setup or am I going to need a two piece handguard? Here is a picture of my piston system..

I am not familiar with the piston design on that gun.  Will you need to remove the handguard to clean up in piston body, or can you do it from the front end?

I'd bet a DD Omega Piston rail would work. Shoot Daniel Defense an email, they should know.

There is a removable plug to access the piston for cleaning. Its on the muzzle end of the gas block, gray in color with a black button.

Thanks, I will check with DD and see what they have to say..

I have the adams arms piston kit and the troy trx rail works perfect. And it's free floating.

DD was closed by the time I called. I did see a rail system on their site for piston uppers. They come in 2 sizes with the large fitting a Bushmaster. They only have information and pricing for the small rail on the site. I sent an email requesting information and will update on this later.

I talked with someone at Troy and they don't offer a free float rail that will fit a Bushmaster.
