Newest project need some advice....IZZY build
Picked up a IZZY light kit a while ago. Argy barrel but most the rest of the parts are izzy. I installed it on a DCI receiver but when I screw it in, I'm left with a gap between the barrel and receiver (shown in red).
Are there such things as shims for this? Is that my best option? Who has them?
Also what kind of front sight/gas block is this? I received a izzy gas plug but it doesn't fit and I had an extra imbel gas plug and that doesn't fit. WTF
Any ideas from the experts??
