Anyone with FIRTSHAND polymer AR lower experience?

[TrickyNicky]

Get your lowers sent to D&T and you have nothing to worry about, Rightwinger and AK guy are top of it. If you got it sent elsewhere you may need to ask them to mark them down as receivers instead of rifles.

Thanks!! So if that stripped one is simply listed as "receiver" I can make it a pistol or rifle at will. Is that assumption correct?

Yes. It is now clear you can go back and forth, but technically [i]only as long as it starts as a pistol[/i]. It does not have to have a pistol type receiver extension to be a pistol -- but would not probably be a great idea to have an stock on you while in pistol config with normal rifle extension, unless you also had a rifle upper to match up..

JoeBobs has a great price on BCG... PSA seems to almost always have some kind of M4 style upper for sale.
Might be better off mix&matching for best pricing.

[quote name='reed1285' timestamp='1351351668' post='834476']I put a spikes tactical lpk in my new frontier poly lower. The takedown pins are super tight, to the point to where im gonna have to take a small drill bit to open them up a bit. I mean they are TIGHT. Have to use a rubber mallet to slide them in and out for takedown.

I also had to take a dremel with a small sanding wheel to open up the magazine release slot on the lower as well. The mag release from the lpk wouldnt even go in until i did that.

Aside from those two things they are cool i guess. Lightweight thats for sure.[/quote]

I just got a New Frontier yesterday and had to throw parts in it as soon as i got home. I had the same mag release issue and I also used a dremel to open it up.

The material appeared very thin around the hole and i think you could go through it sanding at high speed without taking good care. I did a little and test fit until it functioned. after that everything else went in the lower perfectly.

Well I just found out my Frontiers came with commercial spec buffer tubes instead of mil spec. Found out by ordering a mil spec MOE buttstock and having it not fit, my bad.

Not that big of a deal, I'm going to send it back and get the comm spec but figured it may be helpful info for anyone considering upgrading.

I don't understand that. Threads for commercial and mil spec tubes are supposed to be the same, are they not?

It wasn't the threading that was his issue, it was the stock he bought afterwards.

Correct, the mil spec buffer tubes are 1.15" and the commercial specs are 1.17"
