As far as the firing pin, we use 17-4 S.S. and precipitation harden them.  We spec straightness at .005" over the length of the firing pin.  If you have any issues w your firing pin, hit us up, and we will get you sorted [email protected]

Not necessarily an issue, I’m running a hiperfire trigger and am seeing that they are notorious for being rough on firing pins.  Just want to know where and how to pick up extras to throw in the range bag.

I took mine out and measured it.

2.646 OAL
.153 large diameter
.103 small diameter
2.416 from tip to shoulder

Pretty close to a Wilson pin from what I can tell.

Just emailed about which style upper (glock or colt) would be best as a starting point.  NFA has the C-5 MP5 9mm lowers out

Stern Block Install feedback

If you install them right, they work fine...
View Quote
NOT TRUE!!!  At least in my case.  I have an FM upper that hits the feedramp portion on the Stern Defense adapter in most of my lowers.  With the bolt installed you can't even install the rear pin as there is too much pressure against the feedramp on the adapter.   I did find an Anderson lower that allowed the adapter to work with the FM upper but the bolt was still rubbing against the adapter feedramp.  I took enough off the feed ramp so it no longer rubs and it seems to work fine but only in the one lower when using the Stern adapter.

Pretty sure my FM upper is slightly out of spec because even with the bolt out of the upper it will not lock down on most of my pistol lowers.  Just the one Anderson with the Stern adapter and on one of my two PSA Glock specific lowers.

FM has offered to replace the upper or refund my money but I'm going to run it for now and see how she goes.

Rifle Gear in Plano, TX, has had them for several months. They look great but I don't know anything about them.

ETA - sorry, when I posted I didn't realize this was already a 6 page thread with a lot of info in it.

I have a Question for you,

i like to have spare parts for my guns, and think of buying one of your uppers, I would like to have at least one spare firing pin spring and retainer, but cant find them
on your website or at Brownells, which style or make do you recommend???

thanks for replying

FM was nice enough to send me an extra firing pin, but doesn’t look like they offer them for sale separate yet.  I ordered a couple CMMG pins from PA and they look almost identical.  Haven’t run them in the gun yet, but they fit perfectly in the BCG.

Good to know, thanks.  I was actually looking at the CMMG pins the other day and was wondering if they would work.

Okay everyone, I ended up emailing FM and conversed with Paul a bit (very responsive CS by the way.. weekend hours at that!)

Something is up with their account here so that is why the lack of response apparently. Passing on info he told me:

Billet lowers going to Primary Arms and will be available this coming week.

Colt bolt assemblies are shipping to Brownells on Monday so those should be available shortly as well.

Any other questions hot up their contact info on their website.

I was told, again, that the Colt bolts were shipped to Brownells and ready to go. I talked to Brownells today and they told me 30-60 days before their in stock?

Have the billet lower in now.. I'm super impressed with the quality of this thing WOW. The LRBHO is pretty slick.

Everything is overbuilt, mag release, bolt stop etc.

So far my 8.5" build without a pistol brace and with a standard carbine buffer is at 5.6 lbs.

So right around 6 lbs total I'd say.

They were sent, same as the Colt Uppers, its like Amazon there, takes a while to make it out of the warehouse, then to marketing for pics, then they go live.  Suspect maybe a week, will ping them tomorrow and advise.

They've had the pics loaded, available for backorder for quite awhile now. I already bought one of your barrels from DSG, and I really want to pair it with one of your bolts. But yet I'm still hearing another week.

Nice!  Good luck :)

My daughter and I took my fm upper/NF Glock lower out for a beat run last weekend.  700 rounds, hot and soft loads.  Only had 1 FTE, other than that...flawless.  Also shot a uspsa league night..flawless :)

Hope they will ship your soon.  I’m still waiting for my 33 round Glock mags I ordered on 3/5.  They keep pushing back my etas.   Now it’s mid next month :
