Fn a5

Looking to build a set of A5s.

Ive found some really nicely factory finished police model receivers for a great deal but I also found some "unfinished" receivers for half the price that just need a little love and hot blueing.

I've never blued anything and these projects are meant to be lifelong keepers i can take extreme pride in.

My question here is: how hard is it gonna be to get the unfinished receivers hot blued? Would it nake more sense to just lay double for the factory new policereceivers? I mean the pricing isnt bad by anymeans but im at a cross road here.

I've also got a large plastic troph i figure i could use to do an electrolysis bath on the unfinished receivers to descale the corrosion off of them..

At the moment i'm thinking maybe I should just treat myself to the nicer of the 2 options 🤔
