I think I have mentioned this before but one of the A3s I got from CMP had a two groove barrel and the first time I looked down the barrel I almost went cross eyed. Plus, it looked like a rusted up iron pipe. Talk about a strange sight. It didn’t shoot well either.
Anyhow I found a NOS four groove barrel with the same mfg. date, full of cosmoline. I had the CMP Custom shop replace the barrel and I think it could now shoot better than I can hold. Now I need to find one of those USMC front sight blades to help out these mature eyeballs.
