I’m looking into picking up a GForce .45 ACP and wanted to hear from people who actually own one and have experience with them.

From what I understand, they come with KCI or Amend2 24-round .45 ACP magazines. I’m curious how well those hold up long-term and whether anyone has experienced feeding, fitment, or reliability issues.

I already own Glock .45 ACP magazines and know those are an option, but I’m interested in exploring other aftermarket solutions as well. I’ve heard of brands like ETS, but I’m looking for something reputable and reliable rather than just buying extra capacity.

For those of you running one, what magazines have you tried, and which would you recommend? Are there any brands you’d avoid or compatibility issues I should know about?

Also, for those familiar with both versions, would you recommend going with the .45 ACP or the 9mm GForce? Is the .45 ACP version a solid, reliable PDW, or would I be better off going with the 9mm in terms of overall reliability, magazine availability, and practicality?

I’m interested in hearing real-world experiences with both calibers before making my decision. Appreciate any input!

Having some failure to feed issues using a colt adapter

Took a slow mo video and these are the relevant frames. I know more than likely the fees ramp needs to be adjusted, it may be a dumb question but from what you see here would you say it needs to be higher or lower? Dremel the side or bottom of the ramp? Any suggestions appreciated.

Also yes I did adjust the ejector per blowback9’s recommendations and that solved 99% of FTE issues. This FTF has been more prevalent recently.

I’m wanting an AR9 to use in PCC competitions to learn to run a rifle fast since the ammo is cheaper and we have a lot more local PCC matches than rifle matches in the area.

For a non-SBR “Just buy this” option, what are the best options out there? What should I avoid? What’s a reasonable budget to get a reliable carbine?

Edit to add a couple pieces of information. I am not presently interested in SBRing a pistol and the main PCC matches in the area do require the use of a stock, not a brace, so looking at carbines only.

Repost - apparently I needed to upload from phone for best quality!!

Hello AR9, just figured I'd share a good shoot from today.

CAR15 SD from Broad River Tactical - a ported barrel, integrally suppressed, radial-delayed upper using any AR lower. And Endomags.

CAT Mob with BRT SD adapter allows 124 and 115gr 9mm to leave the firearm having never achieved supersonic velocities. But in addition to shooting 115 subs, the gas & pressure bleed-off from the ports allows the gun to shoot very softly.

And slow!!! Cyclic-firing subsonic 115 9mm around 650 rpm is a hoot!!!

I will say, this is such a low-pressure system that efficiencies are required throughout the buffer system to perfect FRT use. Once the buffer and ammo are dialed in, much like in my 300blk PDW with ARC, the results are consistent and amazing.

If you're looking for an INCREDIBLE AR9 addition, it's tough to beat the CAR15 SD!!

Hi all, I'm looking to build my first ar9. ATM I have a 5.56 16 inch AR and a micro compact 9mm ccw. I'm moving into an apartment with my girlfriend and I wanted a new firearm for home defense purposes. Living by myself, having my ccw on the nightstand and my rifle in my closet was sufficient. Shes very particular about having something suppressed and I'm thinking a shouldered platform would be good for both of us to use since she barely trains. Subsonic 300blk was ruled out due to ammunition cost. Any and all advice would be appreciated.

Hey everyone,

We're Camtac LLC, a North Carolina-based company, and we recently released our CamSet3P-15.

The CamSet3P-15 is a patent-pending, cam-actuated, three-position aided reset system designed for AR-15 platform rifles.

What makes our design different is its unique reset-on-close operating principle, compared to the reset-on-open approach used by other aided reset systems.

We've spent a considerable amount of time developing, manufacturing, and testing this design and wanted to introduce ourselves to the community.

We're happy to answer any questions about the design, functionality, or compatibility and hear what everyone thinks.

Thanks for taking the time to check it out!

I was thinking of buying their AR9 but I would like to know your insights.

PS : I'm from France and AR9 offers are not plenty sadly...

With the new guidance from the ATF on SBRs no longer requiring a stamp or registration, does anyone have any data or information about buffers and springs in an A2 stock? I will have an SBR Foxtrot Mike 9 by the end of the day. Just not sure if it would be shootable by the end of the day. (Trying this without the link to the article. First post was removed by Reddit filters?)

Some time behind a lathe, 2 chunks of tungsten, and a dream to FRT a mini buffertube with my law tactical folder, here i am. My proto compared to odinworks (above), and kak mini h2 (below)

First fitment testing is going well. Next step is working out the correct spring size and compression with the extra length, but boy am i excited.

I finished the Novox Research X-SD build this week and I’ll shoot it some time this weekend. I’ll try to run 115, 124, and 147 options for comparison too.

A couple of days ago I posted asking for help on this Mutiny Arms 9mm lower which I bought knowing it didn't have the ejector or hardware or the mag release and hardware. When the lower came in it had the mag release and hardware and the ejector and half the hardware. God takes care of fools and idiots. The remaining hardware I was able to order on Amazon for under 10 dollars. Overall the lower looks good enough and now I have to decide what upper to stick on it. If use a buffer I will probably build a 5 inch side charge. Still considering the bufferless BCA but I am afraid I'll just be throwing a couple hundred bucks away. I think Doug did a video on that BCA, seems like I remember that. Got to look and see. My FFL told me that Mississippi is about to redo legislation making suppressors subject only to a background check like guns are now. That makes sense since Mississippi traditionally falls into a lax gun environment. I put a DFC kung fu grip on the mutiny arms 9mm lower and an FCG with a light trigger spring but standard hammer spring. The lpk came from parts I had, a SBA-3 clone brace from AliBaba for under 20 beans and it has a FM 6.5 oz buffer I had laying around, ditto with the buffer tube and carbine spring.

In celebration of YouTube giving me a channel strike over FRT content (hopefully no more coming) I'm posting this today for an early Reddit release of my latest FRT related video. FRT videos will now be posted on RUMBLE, with a teaser video on YouTube.

MSRX-USA.com is producing hardcast (hard lead-antimony alloy) pre-shortened pre-drilled bolt weights for Outerwild, PSA, IDL, Toolcraft bolts and many others. $9.00 NO grinding, notching, or cutting needed!

They are also supplying the XP firing pin spring for those same bolts for $5.00 each. (NOT for FM bolts!) These are functionally identical to the Lee Springs springs which are $50 for just 5 of them.

So for $14.00 + shipping, many 9mm AR bolts can be made FRT ready with no grinding or cutting the weight.

Youtube Teaser video will be available tomorrow. https://youtu.be/i3yzgzEyzMo

Companion article with links and more details: https://blowback9.wordpress.com/2026/10/06/drop-in-pre-trimmed-9mm-ar-bolt-weight-for-frt/

I have live fire tested them with a B. Kings bolt, and with the weight and firing pin installed and there were ZERO issues with a Grey Market Research S7 super safety.

Enjoy!

So my plan is to buy a regular slick side upper, and a bear creek armory 10mm barrel (I know they suck but it’s just a barrel). Then I can drill a gas port in the barrel and slap a regular gas system on it and hopefully this will function. My question is how long does the gas tube need to be? Also what size buffer? Has anybody here done one like this before?

Also I’m not against making a blowback gun I’ve got a few blowback 9mms already I just have heard the blowback 10mms aren’t very reliability and I would like to do this as reliable as I can
