Is the gun what the seller says it is? For example
if it is being sold as pistol but the receiver
says CM-11 (the carbine version of the PM-11).
Or the seller is claiming the gun is a pre-ban
(not that it matters anymore regardless) and it’s
marked as a PM-11.
2. Are the accessories installed on the gun
legal? This primary applies to semi-auto versions
of the M-11. For example a PM-11 with a folding
stock is illegal unless registered as a SBR.
3. Does the lower receiver look normal or is
it malformed? This primary applies to transferable
full-auto M-11 variants. Sometimes a full-auto
M-11 can be found that has receiver damage
from a catastrophic ammo failure or a poor factory
weld. Some sellers will fail to mention this
to make a quick buck & will pass these off
onto unaware buyers. This usually happens with
guns bought online so be sure of what you are
buying. It’s a good idea with these guns
to remove the upper and look at the welds in
the lower to make sure they are not cracked
Location of two internal welds you should check
4. Do the moving parts function correctly? Check
to make sure when you pull back the bolt it
doesn’t bind up and get stuck.
5. Do all the parts look to be there? Do a quick
check from the outside to make sure items such
as safety switches, axis pins, etc are there.
6. Do any of the FCG parts appear to have excessive
wear? This primary applies to transferable full-auto
M-11 variants. On some FA models the sear and
sear catch may have worn prematurely which can
result in a runaway or malfunctioning gun. Look
in the trouble shooting section for more information
on this problem.
7. Does the gun appear to match the “history”
that the seller is giving? For example if the
seller claims the gun is NIB (New In Box) and has never been fired yet
there is powder residue inside the chamber or
carbon build up you know they are not being
NOTE: DO expect that if the gun has been a safe-queen, it
will need to be disassembled and lubricated, and the rubber or neoprene
buffer at the back of the bolt will probably have hardened or disintegrated
and need to be replaced -- that's to be expected, and it doesn't make it a bad gun to purchase.
