rustybayonet Posted January 17, 2017 Share Posted January 17, 2017 I'm looking to up grade my M&P9 fs. I have used stormlake and they work nice, but I found a good price on an aac. Just looking for some feedback on the aac barrels. Link to comment Share on other sites More sharing options...
RH45 Posted January 23, 2017 Share Posted January 23, 2017 I never heard of them. I know guys that have Storm Lakes, and they seem to have short chambers, and sometimes fit well, sometimes not. KKM is a good drop in, but, in my pistols, they seem to prefer 115 jhp, or, 160 black bullets. Everything in between is 3-4" groups at 25 yards I had an Apex, gunsmith-fit bbl put in to my 9mm Pro, and with 124-125 jhps, it really tries to shoot an inch at 25 yards, but, there seems to always be a flier. I only have maybe 100 rounds through it so far, and I can see it is already wearing in. I have more loads to try through it. In my initial testing 115 jhp, 147 jhp, and 160 black bullets all seemed to want to shoot 2-3" at 25 yards. The worst was coated 122. I think they were like 4-5" at 25 yards.

rustybayonet Posted January 23, 2017 Author Share Posted January 23, 2017 From what I found out is that the barrels are considered a "duty barrel" and not a percision barrel but more like a glock barrel designed for reliability over accuracy. So I pass Link to comment Share on other sites More sharing options...
Mully383 Posted January 23, 2017 Share Posted January 23, 2017 I just finished off a new m&p. It has the apex gunsmith fit in it. So far I'm loving it. Shoot 5 in groups with 124grn pull downs that where a load for another gun. Working up a 147 grn load now Link to comment Share on other sites More sharing options...
kcobean Posted February 2, 2017 Share Posted February 2, 2017 I bought an AAC threaded barrel for 9mm to put a Surefire Ryder9 Ti on. Seems to be a good quality barrel. Dropped right in and shoots accurately. Only complaint is that the thread protector doesn't want to stay on, so I either have to loctite it or keep checking it every few rounds, which is a PITA.

I have an M&P45 with the threaded barrel, I used some blue loctite, so far so good. Link to comment Share on other sites More sharing options...
shooting for M Posted February 8, 2017 Share Posted February 8, 2017 The blue locktite didn't work real well on my storm lake threaded barrel. A 1/2" o ring did the trick, like $0.50 at Ace, about 1000 rounds so far and it stays tight.Sent from my Moto G (4) using Tapatalk Link to comment Share on other sites More sharing options...
Avedis Posted February 8, 2017 Share Posted February 8, 2017 what is the best price you've found on one? Link to comment Share on other sites More sharing options...

shooting for M Posted February 11, 2017 Share Posted February 11, 2017 Does the o-ring just go down at the shoulder of the threads? Yes. Someone somewhere suggested scuba because they were made from a better more heat resistant rubber. I don't know much about those, but the regular ones seem to work fine for me.Sent from my Moto G (4) using Tapatalk Link to comment Share on other sites More sharing options...
Tarkeg Posted February 11, 2017 Share Posted February 11, 2017 The good scuba o-rings are called "viton" and are pretty durable. Believe it or not, a short wrap of good teflon tape on the threads will work fine. Doesn't last forever, but easy to replace. Link to comment Share on other sites More sharing options...
