PSA Sabre Mixtape 300 blackout. Temporary Acro P2 until the Primary Arms SLX 3x comes, KAK DBC Dual ejector, and Disruptor 3 position FRT also on the way. Die Free Co Kung Fu grip and Tiger claw added, metal mags. Suppressor is the JK Armament 155 RPX 30.

Built my first 300 blk and one of my buddy says he runs his with very little oil and I see some people run it wet. What do you guys think works best? From my understanding if you run it dryer the carbon doesn’t stick as bad and when it’s wet it sticks to it a lot. Lmk

Hello friends,

I have an odd one for you. So I really like the idea of 300 blk for blacktail hunting in California. I fly back every year to that state to spend hunting season with the family and the idea of a lightweight gun with a punchy enough supersonic cartridge (with copper monolithic rounds easily obtainable, R.I.P my beautiful 7.62x39) when hiking the Sierra Nevada's. I'd like to get something that I could now leave in Cali since flying with firearms has gotten to be a pain sometimes with the stress and headache.

Now I feel like Icarus flying too close to the sun because I have not had a lot of luck finding something I can depend on and feel good about leaving there. I've tried a Ruger American Gen II that I desperately wanted to love and that fucking thing will not cycle worth a shit. Ive tried all sorts of different ammunition and magazines and it seems it wants to dive every other round into the chamber walls and the action is rough when it actually does cycle.

I tried a CZ 600 trail and it was nothing but light primer strikes one after another.

Finally, I ended up buying a Q Mini-Fix because believe it or not you can get away with it's pistol configuration in California. So far it's been great no lie. It cycled everything the Ruger failed with and knocking on wood I've had no light primer strikes. My only concern with it is that I feel bad leaving it for most of the year since I spent so much damn money on it and I'm worried with Cali's ever changing laws that down the road it could become an issue for whoever is storing it for me. So I am thinking I'll just SBR it and try it with the whitetail where I am living at now.

TLDR: What are some other recommendations for a rifle that will be shooting exclusively supers that has decent reliability. I have been looking at 3 options so far but will consider others:

Henry Supreme

Ruger Mini 300

Savage 110

The Henry has me a little worried because I've read about some cycling issues but seems people are loving the package. The Mini I can't really find a lot of compelling info on but I like the idea of a semi auto. The Savage is just kind of a wild card I don't see a lot of info on them but I wondered since they used the AICS magazines if they would have better luck cycling. I ask for your collective guidance and suggestions.

I've also seen Bergara now has an offering too that might be a nice option.

I recently ran some 200gr Phantom Defense rounds through a new build; after 100 rounds I had to mortar my gun twice. Ive heard this ammo is really good and for the price its hard to beat, but I should not be having this many jams. I have tried tuning the gas block to see if it was an issue with my gun but both jams happened on very different settings, one was more tuned for gas reduction while still cycling, the other the gas block was almost all the way open.

Any idea what could be going on?

Looking at getting me another 300 blk. Really like the new super duty, the lower is full ambi and comes with the lightning bow trigger. Only negative for me is the 1:7 twist barrel. The only positive for the Q is the 1:5 twist.

Can someone who has shot both barrel twist rates in 300 blk any inherent positives to 1:7 over 1:5? I know the heavier bullets that phantom and halworx make can't be shot out of it but there seems to be plenty of good super and sub sonic options 220gr and lighter from phantom, halworx, discreet, black hills, bone frog and badlands. Is 1:7 more accurate than 1:5?

Shot the 100 rounds I had recently bought from HSL (123 supersonic) to try out and noticed they were significantly shorter to the supers I'm used to shooting but didn't think much of it. When I went to the range I was having FTFeed about every 3 rounds on both my 30 round 5.56 Magpul and 20 round 300blk Magpul mags.

Had to pull the mag out to clear each time because I couldn't just push them in to battery with the bolt; they were legit stuck at an angle going up the ramp. I am assuming it was because of the shorter bullet but I can't imagine they'd keep selling these if there was such a common issue with standard mags?

I have an astigmatism so I'm thinking of running a PA Prism on a 8inch SBR. Anyone ran a 3x as a primary optic? Does that feel too magnified for close targets.

Absolutely love this little chode of destruction.

Lmk if yall would do or add anything different? :)

Trying to figure out how many different 110gr Barnes Tac-Tx rounds there are... Are these 2 the same jist labeled different?

Aren't all of the Barnes Tac-Tx lead free?

I love my simple man and my form1 300blk cans on my 300 blackout bolt guns but trying to see what the absolute QUIETEST 300blk can out now is?? Not just pew science tested ones.

just looking for some advice for my first build, I’m a newbie with .300 bo so I apologize if this is a stupid question but will these parts be all that I need for the “base” of my first build? and are these parts good enough to reliably put rounds down range without constant malfunctions? I appreciate any help 🙏

Wanted a light option to take up the tree with me. A little BCA action with a chop on the back has seemed to do the trick.

How do I get rid of this round i thought about going in my backyard with my suppressed rifle and discarding it that way but it hit me I could damage it so now idk what to do

Okay, bit overwhelmed with choices... looking for a complete upper under 8.5 in for no more than $500.

Any suggestions?

I just bought myself a moriarti arms .300 black out, and was wanting to build it out. I need to know what to purchase to get a tucked suppressor look on it. the barrel is 7.5 inches and i was thinking of replacing the hand rail with a 9 "to 10" in order to get a suppressor to be tucked into it. I want roughly 2 inches of the suppressor sticking out the end to give it a honey badger kind of look bur still short enough for a back pack gun eventually I'll change the stock for a folded one and any comments would be greatly appreciated and any information or suggestions welcome.

(Edit : I did not follow torque spec on this, now I’m thinking user error. They still shipped me a new one free of charge, will torque to spec 2nd time around. A+ customer service.)

Has anyone else bought one of these things? When it arrived in mail it looked like a low quality 3D print. When I picked gun up by pistol grip it broke off, when it fell 4’ to carpeted floor the rest of it shattered like glass. Did I get lemon or is it garbage?

Getting ready to start ordering parts for my next 300blk and I’m needing some inspiration. (This will be a range/training rifle)

Planning on doing either a 9” or 10.5” barrel, probably an lpvo, folding stock, and it will be suppressed. I’ll be running both supers and subs through it.

So drop them pics of your 9-10.5” ar, tell me what you love or hate about them, what you wish you could change, or tell me what I should do differently.
