In my years of gun ownership I've learned three important rules when it comes to FFL transfers, and FFL's who only take from other FFLs and FFLs who tack on percentages in the name of sales tax / mark ups etc.
The rules are in order of importance.
1) no matter what it takes, how much it costs or how long it takes to travel, ONLY use LRB for transfers.
2) see 1
3) see 2
These guys are hardowrking, honest decent affable folk who not only manufacture American made receivers for M14 and AR15, but also thoroughly believe in the principles that I do (arfkom code of life) - e.g. If the law says FFL's can receive transfers fro mindividuals, then there is no reason to add another layer of BS to the process.
I love going there to chat, browse their surplus gear, and drool over their receivers.
I feel that my transfer fees are promoting the values we all espouse here, by promoting them and what they do.
I hear dutchess county is friendly as well, and I don't doubt there are other FFLs that are great places to do business, but LRB is the only way to go for me.
