I've started building my first AR, and have some questions about the Buffer Tube.

I'm looking at an 18in barrel from APOC Armory, and from what I understand one needs different buffers for different barrels. Do different buffers preclude you from using different stocks?

Pic is what I'm looking at building.

A few questions about vented barrels...

If you have a vented barrel, with a vent very close to the end of the barrel, is it not possible that this will adversely affect the stability of the bullet as it leaves the barrel? After all, there's a sudden gap in the rifling and then it starts again? People keep harping on about how the crown area is possibly the most important barrel part accuracy-wise?
Is the area where it restarts given special attention to ensure the rifling engages more gradually when they vent a barrel like that? Or is this a non-issue and I'm overthinking this?

(ignore the silly dual 1911 abortion I'm using as an example)

i really hope that with the release of the p10s that p09 and p07 mags become cheaper. i'd hate for the p10 to become the vp9 2.0 where the "selling point" was that you could use p30 mags with the vp9.

then again, happy merchants gonna happy merchant, i guess.

For that guy asking about the CETME rifles, look no further.

You gotta roll your own, but it can be done. You'll need a parts kit, and to buy a receiver and some other things.

How do you like it? I watched the whole series when it was first posted. Ian and Karl seemed really proud of building it, but luke warm with the rifle itself.

I mean, it's a roller-delayed 5.56mm. In theory it's not really doing anything different than an HK33/HK93, neither of which were ever massively popular. It's a unique piece with some retro cool factor, yeah, but it's not gonna compare particularly well to say, an AR15.

New and interesting malfunction from Kel Tec

I assume it was extraction/ejection. It looks like the round went off, extracted, but didn't leave the rifle.

I tried an SU-16 and it cycled like it hated life. Not sure why the case didn't fly out as I would expect, but with a rifle that cycles as violently as the one I tried (assuming mine was a regular example, I don't know, haven't shot other examples), if the case doesn't go a mile out and slips off the extractor early, the bolt coming back and closing on the empty case at just the right angle could crush the case like that.

Just speculating, OP should return and tell us more about it.

General weird malfunction thread until then, I guess?

It kinda felt like the gun was like "PARTY HARD YEAH" in that "I don't expect to live that long since I'm made of cheap parts, but I'll do my best until I spontaneously disassemble" kinda way.

So I'd expect it to work with no issues in any situation with any ammo until all the guts shit out from any available orifice.

After own and built a few AKs and ARs it always come back to KAC’s SR-47 – basically an AR minus bolt hold open on last round and takes AK mags. After learning KAC had no plan on selling it to civilians and only 7 units SR-47 were made. I looked elsewhere.

Do you have a micrometer? I'm curious about the compromises PSA made in the dimensions of their 7.62x39 bolt. 7.62x39 has a larger case head than 5.56x45, which supposedly is why CMMG went with a larger bolt and bolt carrier group in their Mutant.

I don't have a Micrometer, only the caliper there are plenty of 7.62x39 shooting AR-15 uppers, I think CMMG went with AR-10 because of the mag well change since they are on AR-10 base why not mod the bolt to work with 7.62x39

Our most common pistol designs shooting full power ammo are by virtue of their specific locking systems not using fixed barrels. This has some obvious drawbacks, from losing some inherent accuracy to being unable to statically mount sights. Fixed barrel designs also tend to have less (comparative) recoil due to the fact the bolt has lower weight than the entire slide which moves on the conventional designs.

However, fixed barrel designs for center fire autos are few & far inbetween.
The most recent one would be the Korth PRS. Costs a pretty penny, but virtue of the name alone, but supposedly low recoiling and accurate.

I love the look of the Remington model 81 but I don't want to use an archaic cartridge. I want to convert one to a modern cartridge, possibly 10mm Auto since the 81 is available in .30 remington, the parent cartridge of 10mm. Can anyone tell me if the barrel is one piece with the takedown interface, or if it is threaded/pressed/pinned? Also tell me I'm dumb and don't need more projects I don't have time for.

>short answer
Start handloading.

>long answer
I'm sure the Rem 81 is a fairly strong action, but the cartridges were loaded usually under 40k CUP. Few modern rounds are that mild, but I don't think it would blow up the rifle to chamber it in another similar rifle caliber. Since it's a long recoil, I severely doubt 10mm Auto would cycle it; more than that, the action is meant for rifle rounds and getting it to feed pistol ammo would be another headache. The 30 Rem is similar to a 7.62x39 in muzzle energy, but the case is bigger and lower pressure and the bore is 308 instead of 311, yet I would likely start there if you do want to convert it somehow. It'll be pretty damn expensive either way to have a barrel made or the original rechambered or bored out and sleeved or whatever you end up trying. It'll be honestly a shitton more than a press, dies, and brass.

Also, cutting a rifle round barely halfway up the case body and "parent cartridge" is a bit of a adventure time jake-rubber-band-for-miles stretch when you're going for something that can cycle and feed in a rifle...
>> No. 102074 ID: fb893e
The easy answer is to reload. Get one in .35 Remington so you have an excuse to get a Marlin 336 and reload for them both.

I actually just got myself a marlin in .35 rem for christmas. Going to reload it with my cast 158gr flat noses I use in .38spl/.357mag.

>> No. 102080 ID: a4650c
>.30 remington, the parent cartridge of 10mm

And also the parent cartridge for 6.8 SPC, if you wanted an off-the-shelf caliber that'd be actually really handy in a little takedown gun like that.

Afaik the takedown assembly/barrel extension is probably pressed/pinned. Not certain, but if push came to shove a good machinist should be able to salvage that part and assemble it to a new barrel. I've seen K31s rebarelled by reusing the chamber end, anything's possible.
>> No. 102081 ID: fb893e
>>102078
You. I like you. I don't reload yet, but doing that is a long term goal of mine once I do. I have a soft spot for Marlin 336s, but don't/can't hunt with a rifle in my state, so a .30-30 or .35 Remington is dumb. A .35 Remington loaded to .357 Mag levels would be a great, affordable plinker.

And I could get a Model 8/81 and try to make it run with reduced power loads.

So I'm massively depressed because I just bought this, I'm in love, and I can't shoot it because I've injured my back. I can't even hold it offhand, but hopefully I'll be good to bench it in a week or so.

Question is, am I stupid for thinking this could be a decent DMR? Like maybe a poor man's EBR? I'm thinking of getting trigger work, and an SWFA SS 3-15x scope. I already have 15 mags for it, and I'm thinking of getting more. I just like the way it looks and feels. This is my first .308 rifle, so I'm actually a little intimidated, but excited too.

Update: I finally got out to the range. Rifle is good to go for DMR kind of stuff. From a rest it does 1.5" groups at 100m. I'm sure I could get a bit more by reloading, but not likely as of yet. Going to save up for good glass, but in the meantime, scored a scope from a sniper buddy of mine in exchange for some computer help (kek). It's the SWFA 10x I was originally going for, but this is the side focus model. I was going to mount it, but I just realized I have no idea the right way to do it. I also don't have a vise, so I guess I'll have to wait a while to get more done one it. Also, does anyone know how to remove the rear sight? This scope has a nice eye relief, but with the sight on, I either have to get taller rings, or I have to get a spacer for the stock. I'm also going to make a cheek pad from foam. I would order a cheek pad, but that seems not worth it when you realize that this is done all the time on the M110, at least from what I've seen.

To be honest, dealing with this has shown me that while I may know how to do the firing solutions, I have no idea how to do deal with the actual equipment. I've never had to mount my own optics. The one thing I don't think it will need is a new trigger. I seem to do well enough with it.

Sweet dude. Glad you got a good shooter. 1.5 MOA will still get shit done.

I shot a Century CETME thing a few weeks ago and it was pretty fun. The usual gripes about the G3 pattern guns, recoil and trigger, wasn't bad at all.

Damn, I love those Marlin Camp guns, really wish someone was making a classy wood and steel .45 carbine these days.

OP's Storm is nice, that is a super reliable and fun to shoot carbine, but most of the options on the market, like the Hi-Point and Kel-Tec carbines, are pretty craptastic.

CZ's Scorpion Evo 3 is extremely awesome, but pretty expensive. I'd love to see Ruger or Marlin bring a modern version of a wood furniture camp/ranch pistol carbine to the market in 9mm and/or .45ACP, I'd be all over something like that.
