Hello I recently bought a Bushmaster Ar 15 shoots 5.56 and has a top rail with optics. It has the generic rounded handguard and I would like to change this and add a quad rail. I was shopping around and my local store had 200$ and up quad rails etc. I stopped by Gander Mountain and found a quad rail from MFT for $60. Why the price difference? is it the brand or the material it is made of? I noticed the MFT said military grade polymer.
Thank you.
Thank you.
