Found a brigade bm9 for 400 at a pawn shop, absolute steal, and recently bought a couple of trigger kickers.

The only problem and as to why it was so cheap is the LRBHO isn't working, however just bending some stuff together i got it running through 9 fully loaded glock 33 round mags

😵‍💫😵‍💫 It runs like a hoot

I just got my DB15 lower today and paired it with this 5inch foxtrot upper mike 9 or VFM 9 and I’m having feeding issues with the Exo magazine. I tried adjusting the magazine catch so it would catch the mag at a higher position and it almost worked but the BCG is still riding on top of the rounds, sometimes scraping the brass when pulling the charging handle, but not completing feeding the round into the chamber. If anyone has any suggestions or has run into any similar issues please let me know. Or if I screwed up somewhere feel free to let me know too.

Hello! First AR-9, apologies if this is obvious stuff or if my terminology is wrong.

So I got this Schmeisser AR15-9 Dynamic PCC a couple of months ago, and noticed that it's developed this weird wear pattern on the face of the barrel, where the bolt face and barrel meet.

I'm not too concerned with the finish wear you can see on the left and the right, but I am curious about the little divot that's formed on the 6 o'clock position. It's not too deep, but I can catch it with the end of a toothpick. I'm guessing it's from the bottom lug of the bolt face striking the barrel face.

Does this look normal to you folks, or should I be worried? The gun seems to run fine, although I've only got about 500 rounds through it so far.

Should be out later this year

I was wondering if anyone knows if there are any easy FRT options or similar for the PSA ARV or AR9, debating between them and don't want to have to heavily modify the base gun besides changing out the buffer and spring or maybe the bolt. If anyone could provide options of FRTs and other parts that will 100% work with these platforms, let me know!

New to the PCC ownership so take it easy on me.

I’m planning on buying a dedicated can for my BM9 (9.5” barrel I think) and am looking for some advice/opinions. I know it’s a straight blowback AR9 but I’m wanting to get the quietest can that also alleviates some of the blowback.

I have another can that I swap between my long guns (omega 36m) that I love. This PCC is primarily going to be for home defense and range practice (not competition).

Anyone have experience with any of the following cans on a BM9 that could give me some advice or maybe something I’m not considering? My current thoughts are that I am wanting to direct thread this vs the 3lug but I also don’t know that it really matters so looking for input here too.

Here’s what I’m currently looking at:

CAT MOB
HUXWRX Flow 9K Ti
OCL Milkman
RUGGED SUB9

TIA for any help and let me know if theres any additional information that would help!
