Shocker

That's impressive. But it's the show that gave us this: Even before he was aiming through an eye patch

I didn't see anything about a tool, I though they were "permanent" because they have a shorter spring so if you took out the capacity-reducer-thingy they wouldn't feed any more. Theoretically that would be a bonus since if you moved to America you could just get a full-capacity replacement spring. But I've been wrong before.

That's what I used because it was the cheapest I could find at the time, just to cover those evil threads. Loud AF though.

I bought a Springfield Loaded but if the Range Officer was available in stainless at the time (like it is now) I would have been all over that

Match bullets are open tip because its easier to manufacture them consistently. The tip either initiates expansion (hunting bullets with thin jackets) or reduces drag (match bullets with thick jackets). I've been playing with the 77gr Tipped Match King. It's longer than a Match King so there's less space for powder but the ballistic coefficient is better. Depends on your range what is best for you. I also tried the 69gr TMK but my gun likes the 77gr better, plus when I calculated the ballistics http://www.shooterscalculator.com/ballistic-trajectory-chart.php the 69 and 77 were extremely close I read a bunch on the Brian Enos forums before picking a powder. I have AR-Comp which is decent but I've heard good things about CFE also.

I've dyed my sand magazines. I was trying for FDE but went too dark and there's nothing you can do at that point (Rit remover, bleach, OxiClean...nothing). Ended up dying them black.

Thanks, all. It looks like I'll be in the ballpark with a 6" drive pulley. Then I'll leave all those other cans of worms firmly closed.

Unfortunately I can't check much of anything on this motor I have in-hand, it's a GE motor but I guess it's too old for the part number to come up in any searches. In fact the wiring labeling is such gibberish that I'm lucky the old cord was clipped instead of disconnected or I'd have no idea what the terminals mean. The other motors are scattered in other houses so I can't examine. I'm aware of frequency drives but I'd probably try to find a DC motor before going down that path. I guess the comment on speed is a good point. I was trying to hit 30RPM exactly (I think that's what the thumbler runs) but that's probably not critical.

I have a few single phase AC motors laying around that my grandpa scrounged from dryers or something. I figured I'd make a wet tumbler with one but I was curious about speed control. I can gear the RPM down to approximately where I want it with pulleys but it would be nice to be able to fine tune the speed, which would in turn allow me to use different size drums for different sized batches and stuff. Can I just put a rheostat/pot/whatever inline to dial down the voltage? Or am I asking to ruin my motor? The motor is a capcitor start, does that make a difference?

Probably because its so GD cold in there that you might as well be shooting outside...thanks to that vaporware range upgrade... There's no restrictions other than taking the new shooters' briefing. Practice drawing from your holster beforehand b/c sweeping yourself or putting a round in the floor will be an early exit

Paste it as an image instead of a chart?

That's what I meant. NRR 19 wasn't enough indoors and if i plugged underneath them there was no point in having the electronics

Price went up but still a nice set of muffs. I thought my Impact Sports were totally inadequate but the Impact Pro is decent. Not sure why mine are red and these pictured are green. Maybe an update?

Shield plus Apex

That would work. If you pick a non-collapsible stock (like the Magpul fixed carbine stock, or a rifle stock depending on your receiver extension) that's one less thing to fret about. I got my lower first, just because I hadn't found an upper yet. When I found my unpinned upper I transferred my lower to my brother with an SP634 until I could make it compliant then transferred it back.

That set screw, in effect, is starting to pull the trigger for you - it reduces creep and weight by reducing sear engagement. So just be careful how much you adjust.

I built my piston gun with MAGPUL furniture, Geissele SSA, free float hand guard using a Spikes upper and Anderson lower for about $1000. Optics extra. If I did it again i could shave 100 or so. Go with a mil spec trigger and shave another 150. DI gas system another 100 maybe.

It was $115 on Black Friday from both Geissele and Primary (free shipping from Geissele). I got my SSA during that sale which the G2S is supposed to mimic - I was trying to get a G2S at the time but they were sold out If it was me I wouldn't be able to wait another year tho...

Huh, I hadn't heard that. The MSDS between regular vs fireblock do look mostly the same, although with different percentages. There are a few additions/deletions that someone that took more chemistry classes than I did could say if they are important.

Interesting follow up http://www.thefirearmblog.com/blog/2015/09/01/kalashnikov-ak-15-saiga-107-review/ And this was in the comments on that same page http://world.guns.ru/civil/rus/saiga-107-e.html

Great Stuff makes a fireblocking expanding foam also, might be a little easier to apply. It's not the regular Great Stuff but I found it at the big box stores when I needed it to finish my basement.

That was my experience this week too. Except it was 30 minutes to find out they didnt have the powder I wanted.

Same steel as most benchmade. Looks like a nice flipper with a bearing system although it doesn't say if the bearings are in races or not.

I got my Spikes upper (with the door and forward assist) for something like $65 from Primary Arms because it was "blemished". Palmetto State Armory also sells blemished receivers if you aren't worried about cosmetics. I never found any issue with my blemish other than I think it's missing the Spikes logo near the charging handle, and you still have their full warranty regardless (EDIT: perhaps Palmetto does NOT have a warranty [see below] but Spikes does). As far as the carrier I have an spare nitrided carrier (only the carrier, the bolt and small parts went into a piston gun) if you want it shoot me a PM.
