You do realise that is over 6 years old right? Back in 99-00 there were some issues with Win q3131. AFAIK and based on the reviews on here I would not hesitate to use it.

If I remember correctly, there were two types of Q3131 available. Q3131 and Q3131A. Q3131 had problems while Q3131A didn't experience any problems.

The current batch of Q3131 is new production. The ammo made by IMI and sold by Winchester as Q3131A is not available anymore. There's so little of the older Q3131 out there, that I'm pretty sure that Armalite is talking about the current production stuff.

Has anyone delt with any of these problems and what were they? Was the ammo Q3131 or Q3131a? What lot/year? How many rounds malfuctioned per box?

Thanks to Marylands AR15 Shooters Site. "However there have been problems with some lots, mostly made in 1999." "These potentially 'bad' lots have been identified as: PD50, PD90, PF40, PC22, PG62, PF52, PF11, PL31, & PN02." This was Q3131 ammo, not Q3131A. |

A bunch of the last batch of Q3131 made before Olin turned over Lake City to ATK/Federal was bad. The burn rate of the powder was wrong, and there were a number of wierd problems with it as a result. A few of those were: high pressure, blown primers, black soot blow-by, difficult extraction, failure to cycle, and failure to eject. Carbine gas systems suffered more than rifle-length gas systems. This affected one or two lot numbers of '98 ammo and a bunch of '99 ammo.
Obviously, this affected only the US-made Q3131 (at the time, Lake City was operated by Olin/Winchester, and this ammo was made there), and NOT Israeli-made Q3131A, which was first imported in '98. '99 was the last year of Lake City-made Q3131, and the last year it was made at all until Olin got a US military secondary supply contract in 2004 due to the WoT. The new stuff (2004-current) is fine. -Troy |

In that PN02 lot I had one box that had 2 blown primers. I had to stop testing the next box (I was running through my chrony) when I noted a MV reading of 150fps FASTER than M193 spec. I didn't even finish testing the 20 round box (I was not interested in any more blown primers or risking a Kboom). |

I feel good enough about Q3131 to buy 1000 rounds from ammunitionstore.com yesterday. This is obviously is an alert on an old lot. Thanks for the thoughts.
