I would like to get a flat top upper.
that being said I am open to suggestions. here are my specifications below.
if in .223, able to handel heavy 69-75 grain bullets
a barrel long enough to wring out the bullets optimum performance, but ,I don't want a hocky stick
if NOTin .223 what calibers are available that will function in my standard bushmaster lower?
I would like to switch back and forth from my A-1 upper to my new upper.
it will probably be toped off with a decent night vision scope so low to zero flash is required/anticipated so I will probably need a devise at the end.....recomendations?(I don't need or want a can)
the range of target will be 50-300 yards...longer shots not required.
freefloat ofcourse, but who makes a decent hand guard?
this will not be a benchrest beauty, this is going to be a working gun so advise accordingly.
btw I am in law enforcement but this is not for on duty applications....more or less for the zombies......(we really need a zombie icon for this board)
thanks for your input.
14.5"-16" Colt/LMT/CMT/Stag in 1:7 for a 5.56MM ( 75-77gr ).
Personally, I would go with a 16.5" 6.8SPC.
If you would like a lighter upper package I would recommend Denny's Global Tactical Operator mid length gas system with a mid-weight contour, Vortex FS, LaRue 9.0 or 12.0 FF rails, TangoDown VFG, CMT M4 upper, LaRue fixed BUIS and Colt M16 BCG with Wolff power extractor spring.
For a more accurate upper a RECCE 16-inch heavy barrel contour with a mid length gas system either from Denny, ADCO or Noveske Rifleworks with the same package above.
If the ammo availability is better for the 6.8 mm SPC a PRI upper would be nice.
My 6.8 mm upper project is on hold because ammo is still hard to find, I could only get low quantities from SilverStateArmory.com in Pahrump, NV.
Good luck on your project.
