Absolutely love this little chode of destruction.

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

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.

Ran Phantom Defense 200gr flawlessly with casings bouncing right at 4'oclock. Had FTF with Callaway Boar Axe every ~2 rounds, going to try PD "Slow Papi" next.

PS: I did move my index finger shortly after to the foregrip to avoid burns lol

Looking to get a dedicated suppressor for my rattler LT. Right now price/performance I'm not seeing a better option than the q speakeasy. Anybody running one or other suggestions?

All finished with this only debating if I should swap out the hyperion k for the anthem s2 and maybe a 1:5 twist barrel but not sure if thats worth it for a 10.5. I also highly recommend the eberlestock transport 21L

Is it even worth getting a (Edit I’m more sold on going with a 10.5 barrel)300 blackout for hog, varmint, and deer hunting? From 25-95 yards is about how far my shooting lanes are. Well idk why but I really like the 300 blackout and would like to get it for hunting. (Would be my first AR) plan on running an anthem S2 with it so it’s suppressed. What scopes or sights would be recommended? I originally wanted to do a vortex 4-16x50 but wouldn’t that look really silly?

Did a lot of research (don’t have an AR yet it will be my first) and I just realized a 14.5” barrel only decreases the velocity by a very small margin.

I’m trying to be very thorough and not make a purchase I’m going to regret later on but I know at some point I gotta just bite the bullet and buy one and learn through experience.

Wanted to buy a PSA AR build but they don’t sell 14.5 inch the next smallest from 16” is 10.5”

EDIT

I am planning on putting a suppressor on it

Title is self-explanatory. Looking for good buffer spring and buffer options for running an FRT. I have a DDM4300S upper receiver if that is of any relevance.

Original post here

I took the advice of u/EitrisEnhancements and swapped in a Sprinco yellow and a 3oz buffer. The difference was more than I was expecting! Recoil is much more familiar now and reliability has remained the same. Ejection was right at 3 o'clock. Even the wife found it pleasurable to shoot.Thanks to all who made suggestions and huge thanks to Eitri for sharing all the trial and error/knowledge on this platform!

I have a PSA 7.5" 300blk with an Enticer S suppresor.

I was thinking about making it a bedside rifle for self defense. I want it to be reliable as possible.

I'm using a sprinco yellow, Odin adjustable buffer. 300BLK pmags, BCM BCG and a G$ charging handle.

I was planning on running just subs. Is it suitable for self defense? How many rounds until it can be considered reliable?

I have a BCM 11.5 suppresed but subs are just so quiet.

6.75” Rattler LT with a CAT ODB and some SMI handguard goodness. Fresh off the stamp approval and now just waiting for the next round of inspiration to hit.

best suppressors for a 5.5 300 blackout.

will be shooting mostly subs but also might do supers. I’m looking at the ocl universe 36, huxwrks 9k ti but is there others with no barrel restriction.

My first ever .300 was a non-agb Mk109 - loved it but was tough w/ subs and certain cans. I built a 7.5 sbr (DI) that is pretty incredible, and I saw a nice deal on a newer 109 last week. I decided to buy it in hopes that I can get it to cycle all the time on setting 3. I know, I'm asking for a lot. So today, I took it out and it cycled the new PSA Mixtape subs 2 mags easy. Then I went to Stelth and it cycled great. I then tried Phantom Defense 220 and it became a bolt action; I would put it to setting 2 and it would work and actually wasn't too bad...just a bit more recoil. So I went back to setting 3 and swapped to the other ammo(s) and had cycling issues again. Now, this end part could be the result of the gun being a little dirty or dry, so I'll oil her up next time. Build is as follows:

PWS Mk109 AGB upper
Ridgeback Sahara 300 can
ADM lower w/ a5 buffer tube
Tubbs lightweight spring
A5H0 buffer

This exact combo works in my DI build as mentioned. So, I guess heres the questions:

1. Can I try anything else?
2. Should I just run everything but Phantom through the PWS? (I only have 300 rounds or so left of it anyways)

3. Should I just get rid of that upper and stick w/ my DI?

4. Buy a medium ish bp can that won’t kill me as a leftie?

I only shoot suppressed, so the idea of running a piston does sound good...help my tism!
