How much difference in weight are the 16" RRA R4 Wilson bbl and a Bushmaster 16" M4 type bbl?????

The RRA has the M203 notch on the barrel but is heavy under the handguards so between that and a Bushy M4 about 14 ounces between M4 and HBAR is about a pound.

Between an HBAR 20" and a Govt Profile (A2) 20" is 16oz or a full pound

Between a standard HBAR 14.5 (37.5oz)  and a 14.5" M4 profile (29.5oz) the difference is 8oz or HALF a pound.  

Curiously a 14.5" + Phantom (or Vortex) weighs the same (32.7oz) as a 16" M4 type w/o a muzzle device(32.7oz).

Even if you use a 16" HBAR (40.7oz) for a baseline, the difference (in non-NFA form) between that and a M4+Phantom is 8 oz (it's 11.2 oz if you don't count the FS).

If the RRA only has the notche cut in for the M203 then you're only looking at a weight savings of an ounce or so, for a 7oz difference.
