Thread: Field modifying service weapons

In the war museum in Canberra you will see Vietnam era SLRs with the barrels shortened and the flash hider sitting just below the gas plug.

The heavy barrel SLR designed for full auto bursts is the L1A2.

The L1A1 would go full auto by putting a ring pull shim under the trigger dear, but that would nullify semi auto function. Standard SLRs used on full auto used to split the stocks.
