Hello and thank you for reading,
I recently purchased a Bushmaster A3 16" upper assembly, this is the exact model I purchased http://www.midwayusa.com/viewproduct...tnumber=439349
I would like to run either a magpul MOE handguard or a free floating quad rail. I attempted to install the magpul MOE handguard however it did not fit, there was a clearance issue at the gas block. Can you recommend a quad rail I can use with my current setup or a different gas block I could use with the MOE handguard?
