Pretty wishful, the big names like Midway and Brownells won't have then but some of the little suppliers may. Check Palmetto Armory, they've had things when others have not.
Just gotta wait for them to be in stock and get lucky enough to get one ordered in under 10 mins. I have seen them floating around quite frequently, just have to keep your eyes open.
I am also looking for lower parts kits. Here in CA, the 2ndary market pricing is $150 for a CMMG or RRA type kit. If its a two stage trigger, the price is over $350. People are selling the Ar-15 fixing kits that have like 80% of the lower parts except for the trigger for $100 even. This sort of stuff I never thought would be so rare.
