DPMS has changed the picatinny rail height three times. The current height will not match up perfectly with railed handguards from any manufacturer other than DPMS. If you want a DPMS upper I suggest going with a Fulton Armory Titan Upper. So far they have not changed their picatinny height.
The new Bushmaster LR-308 O.R.C. is being referred to as a relabeled DPMS LR-308. If this is true, what is the receiver’s rail height for this rifle?
The Bushmaster is most definitely a DPMS. They are the same company. This is not the same 308 design Bushmaster had years ago.
I don’t know the measurement but here’s what we know about the DPMS
DPMS manufactures Fulton Armory’s stripped uppers to the original height so obviously DPMS has the ability to create all the variations.
Perhaps one of the Bushmaster members can be persuaded to take a measurement.
