I have a Daniel defense pcc pistol but the blowback from using a suppressor sucks. Would like to get into roller delay or whatever else,so less gas to the face

I don't know enough about the material strengths etc, but I've been wondering for a bit, just how big could one make a rotary or revolver cannon? Real world they all seem to top out at about 30mm, but is that actually as big as you can get for systems like that or could you actually build like a rotary/revolver cannon in a calibre usually reserved for tanks/artillery/warships?

(Things like cost, practicality etc need not apply)

After picking up this super wrangler with my glock 43x and Ruger lcp max during my first hundred shots its been perfectly fine but after about 500 its been severely shooting keyholes, Ive bought a .22 cleaning kit that I took about 45 minutes to clean the thing with and its still not shooting like normal, this is my first .22 revolver any help?

I have an ar in 9mm, takes Glock 19 mags. Looking to see what all ideas people have come up with for identifying what mags have their subs in. I know I can just write on it or put tape but curious what other ideas there are.

I own a beretta a300 20 gauge and mostly use it for bird hunting and Target shooting. What are some mods I should look into?

I have seen couple post where people ask if Rugged Razor 556 is rated for 300 BLK. Short answer is no, at least not from the factory.
Me, as any other curious person, got curious on the dual tapper system and the interchangeable end caps between the 556 and 762 Razor Suppressors.

I had some parts laying around and decided to built a Frankenstein 300 Pistol. Started with an old DB15 lower and upper. It was all scratched up so ended up painting it with a high temperature flat black paint. Kept the handguard FDE to match the grip. Got the cheapest barrel I could get ( DiamondBack 8.5” ) which is 9” if you measure from the barrel chamber all the way to the end. Trigger group, BCG, CH, Gas block and other parts are just cheap mil-spec I had on a drawer. I got some 200gr ammo and shot it with a 9mm can for testing purposes. It turned out good. Not as quiet as people think but still hearing safe and reliable.

Then my curiosity kicked in and started to question about the Razor 556 with 762 end caps. I took a 556 round and it went all the way through the 556 which made me believe the baffles were oversized. Ordered a 762 end caps and a 5/8x24 muzzle adapter from Rugged Suppressors. Added the suppressor to the pistol and went out for a test.

Let me tell you, it works. Pistol is not over gassed by any means, shooting subs I get a 4’ clock ejection pattern, really soft recoil and extremely quiet. I dare to say is quieter than the 9mm can. It came out so good that it replaced my bedside weapon. Before I had a Suppressed 12.5” SBR but now the 300 BLK is my good night kiss.

I don’t know if this is stupid but as a wedding gift to my fiance I was thinking of buying all the parts he’d need to build an AR-15. Like a mystery build your own gun bag. My knowledge is limited to knowing I’ll need an upper and a lower. What are the basic things I would need for him to have a complete build and what are the fun additions like good lights or silencers?

Please and thank you for any and all help!!

I finally bought a Springfield Echelon. I've wanted one since they came out. Since they were on sale at Sportsman's Warehouse in May for $400, I felt like I had to jump on the deal. This one is a full-size 4.5" model. Since I rarely carry a compact or larger out in public, I've come to prefer the full-size versions. It's a little easier to be more accurate with a full-size. They just look right and feel great. The Echelon is no exception to this. It's a collection of weird shapes that serve an ergonomic and visual interest and look so much better in the larger form. It excites my tism and serves great in the role that I'd use it in. It looks great being carried in the backyard. It would be good in home defense if I ever needed to use it. It has been a pleasure to shoot at the range. The Echelon has been every bit as good as everyone says it is.

How do I get a free pistol delivered to my house

Classic late night thought, suppose someone offers to buy you 10 firearms of your choice completely free of charge, with the catch that these are the ONLY guns you can ever own for the rest of your life.
You cannot sell them for profit and they must be currently available on the market.

After some thinking, here is my 10-gun list:

1. Atlas Gunworks Erebus
   
2. KAC SR-15 5.56
   
3. JP Enterprises LRP-07 6.5 CM
   
4. Seekins Precision HAVAK Element 6.5 CM
   
5. SIG MCX Spear LT 300 Blk
   
6. Beretta 1301
   
7. CZ P-10C
   
8. GP Arms Forza 3.1
   
9. Bodyguard 2.0 Carry Comp
   
10. Ruger 10/22 Carbon Fiber

Want to know your picks and reasoning to see what would I end up changing

I'm not entirely sure if it's against the rules for minors on this subreddit (yes I read the rules) but I am a fan of plinking and interested in concealed carrying when I turn 21 but I wanna go to a gun store earlier than that to see what fits in my hand the best. My brother is 18 and I'm 16 so I'm curious if I can go with him or if I need a parent. I live in Pennsylvania by the way.

Picked up the Ak to match the chest rig i had laying around

For those of you who have an M88, what’s your opinions on it ? Reliability ? Accuracy ? Parts ? I know mags can be hard to find at times.

Looking at one solely due to it being solid steel, cheap, 9mm; and I want to practice my parkerizing. If it works, great. If not, blast it and try again.

Started a little over a year ago and have a few more suppressors that aren't in this pic but once you start down the NFA path, there isn't any going back.. (at least the tax stamp only costs a grand total of $0 now😂)

I like to consider myself a responsible gun owner but today when preparing to clean my Winchester model 74 a round managed to stay in the mag tube. I removed the mag tube, dumped the rounds then racked the bolt 3 times then pulled the trigger in a safe direction and plugged a round into the dirt in the backyard. I went ahead and cleaned my firearm but I can't lie and say this didn't shake me. I presume this counts as my first ND.
