L1A1...what happened to the original receivers?

[enbloc8]

NZ Police rightly considered them to be an auto sear. I purchased 1,000 L1A1's off the NZ Army in 1988 and converted them to 'semi-auto only' specs for civilian sale by grinding 1/4" off each end of the auto sear and arc welding them in place. Problem solved and perfectly acceptable by the NZ Police. Subsequent Army civilian sales were stopped by the Government and the rest of the L1A1's were exported or destroyed.

Wow, I thought there were more than 1,000 SLRs on the civvie market in NZ??
