Where can I find an FNSPR A1 NIB for purchase?

G&G Sales, sometimes on GB, but be sure they are listed specifically as NIB. Jerry's Sports Center often times will have them. Sometimes, I understand you can have your local dealer call a mfgr directly and see if they'll sell to him your rifle. It may be slightly higher than what a stocking dealer might get it for, but you never know. My dealer sometimes can do that for me and has for a couple of AR's I've bought. I'm kinda glad it didn't work out with me selling mine - I'm falling in love with it all over again. I think, dollar for dollar, they are a real value when you consider what you get out-of-the-box on these rifles, compared with their sub-moa accuracy. Good luck, and hope you are able to find one. :)
