RN-50 Barrel Test Gun! 

Mark can do all the desk pops he wants and no one gets mad

god damn, olight literally sent every guntuber that optic

Love the BTG. Darn nice finish for a shop prototype/testing “jig”. I just saw the Osight on Demo Ranch. The charger/cover not only shows the charge state of the sight while it’s charging it, but also shows its own charge state immediately after you take it off the sight. Nice feature.

That's a sweet sight from a distance. The real test is bright sunlight outside. Very few red or green dots work well in bright conditions.

It’s funny how a simple drawing gives clarity.

As always, excellent to see another video from you. Thank you for what you do.

I saw an Americana Apparel ad (6 minutes, 42 seconds) for great coats before the video & I gotta be honest, they actually caught my attention cause it had some funny bits, no profanity censors & was informative

Nice video as always Mark. It's always interesting to see what you're up to.

Get good at something you're passionate about and the money will follow. Nice job sir!

I like it Other than rifling the barrel Your video has given me some new ideas on a way to go on my own project A simple semi auto 9mm carbine But I decided to use Sten Mags as I have a bunch of them

I think hardcoat would be simpler to get a known fit with because it has to be held to a very well known spec. But I've only had a few of my designs anodized so I could be wrong.

That is hilarious that you have a 9MM adapter on the RN50! But yes for sighting in at close range it's cheaper than firing 50BMG ammo.

Add a suppressor to the pistol. That would look epic.

Thats a nice looking sight. It charges like my sennheiser earphones. Case charges the ear buds and when the case runs out of juice you can charge that as well.

Those tabs on the accessory boxes are so you can pull them out of the box like a civilized person 😂😂😂😂

olight, when you want both a red dot and a weaponlight that can explode at any given time

You're the third youtuber today who pimped out the new Olight Osight, and I want one!

Love your videos Mark you are the best thank you for the great videos 👍

I have never seen that episode of The Twilight Zone. I guess I now have some homework.

Good stuff, brother!

I cannot express to you how much I have got to have one of those little 9 barrels to put on my RN lower. Wouldn’t mind having a 16 inch barrel in 8mm Mauser too. I know that’s weird but that’s the kind of shit I think about.

@dutchbiker4825 just watching a master builder screwing around teaches a lot who cares what the video was actually about

please test design 2 identical platforms but rifle 1 barrel in reverse and get Edwin to test long range...PLEASE! lol im a huge fan from upside down land austraya and really want to see this like the toilet flush theory...would it be different results on this side of the globbby? ❤

Waiting for the _Buttmaster_ w/silencer conversion for this beast.

thankfully i didnt see too much bad stuff and will vote for bye dhen now

You know had a great childhood if you watched The Twilight Zone and Outer Limits parable shows.

it would be cool to have A GUN THAT CAN shoot any round by simply getting a barrel for the round u wish u could make A whole platform like ar 15 or Harley Davidson type shit u can customize the beep off it in any way u want 50 cal sniper rifle or 22 pistol etc this os dope idea

have you ever entertained the idea of interrupted threads on the endcap?

Have you ever considered that you are some kind of savant? When presented with a complex engineering problem, you often are able to come up with an efficient fix to the problem. When presented with a simple problem however, and you seem to not be able to figure out which way "up" is, ha. Seems like a neat sight. The charging case/ protective cover is a nice feature that I have not seen before. I am sure it will be a popular pistol sight

Make an 8gauge barrel for the rn50 to shoot winchester industrial shells.

Every quarter inch matters!

Lol thanks for doing a video about HoB after I did a bit of trolling in the comments

I won't buy an Osight. It's being forced fed. I have seen it on no less than 12 channels since yesterday.

I just want to know where I can get a Serbu firearms shirt!

Serendipity isn't by accident?

I need the RN-50 2.0 pistol with a 14” barrel in 444 Marlin.. 😬 If that was a success then maybe in 9.3 x 62, 7mm-08 .. somebody’s got to fill the void left by the exit of T/C and their wonderful single shots. One thing I noticed is the break action lever on heavy recoiling rounds has a tendency to impact your finger in an unpleasant way. I think the RN model has that part covered but the cap might be one place that could be improved for mass market appeal. 🤷‍♂️ maybe then it wouldn’t be an RN-50 but an RN-heck yeah or something? RN-BBP Big Bore Pistol

Can you send me one to Australia ?

Probably an optics cover slash charger.

What are you doing with that pound of pyrodex on the bench?

is that not an enoumous ammount of force being applied to the hollow hinge pin? In school we were thought the same force applied to the breech face is applied to the hinge pin.

( RONALD REAGAN ) GUN BAN Anniversary TODAY 38 YEARS AGO ! MAY 19 1986 ! STILL NOT Repealed !!!!!!!!!!!!!!!!!!!!!!!!!!!!

If you ever sell a .50 BMG pistol to anyone including transferring to a gun store, the ATF will ban the sale of steel core .50 BMG ammo. The armor piercing ammo ban only goes into effect for pistol ammo. No one has sold a .50 BMG pistol yet so it's still legal. Please be careful.

I'm not that lucky adjusting a sight on 3 trys

man let me get that step file og

I took Serendipity to the prom in high school

you look exactly like the thingy guy with the hat from twillight zone🤔🤔🤔

Hey so ... because of the way the nfa works have you thought about making an aow that is a double barrel 12ga like from mad max? A $5 tax stamp is way better than the $200 for an sbs. Just thought id mention it since when i kept talking about a trigger that fires on pull and release back in 2011 finally became a thing that maybe if i put this out in the open someone will do it.

Hey Mark...Side folder..45 ACP, LC, Casull. Or 44 or 357 mag..light weight survival backpack type, threaded, Magpul K2 grip (storage), vert grip..hmmmm!

✋🏼🇦🇺👍🏼

200 дешево? :) Да вы, батенька, зажрались :))

How mad does it make someone who sees a gun be deconstructed..?

Adjusting the red dot after a group shot test of the barrel is not really testing the barrel anymore, is it? Kinda looks like you're mixing up two variables here. Would like to know what the objective was for the barrel test as opposed to just sighting in the gun. [edit] Is it me or did the 7th shot keyhole?

Hey, make your AR style pistol/rifle that SIG stole your design from instead of playing around with this. Come on man, we have been wanting it for like 10 years now

Wonder if you could drill holes in the barrel and use the sleeve as an integral sound suppressor

Ww

would you apendix carry that jajajaja

I think you should stop making these pipe gun .50 bmg. My dude you almost killed Kentucky ballistics I understand that it was a hot load. But it shows that your design is extremely flawed in case of a catastrophic failure and you should rethink your design to have a better way for the gun to detonate in case of a failure

How do you replace the batteries when they can lo longer be recharged? I'm guessing they want you to throw away the optic and buy another.

Mark, I would pay good money to watch you do stand-up.

9mm RN50 - Confirmed - "Gun Nut".

Sighting red dot * rough bore sight *Shoot at center bull * Fire round *Resume your point of aim (center bull) that you started with and then you dial the dot over to the bullet hole that you previously made with your last shot. * fire again and you should be just about dead on and then you make a minor adjustment and you’re done within three shots. You should be able to sight in any red dot. Hope this helps some viewers

The King of mailboxes on a pistol goes to......Olight Out of Sight!

Love the Twilight Zone! I have over 90 episodes. 😂😂😂

You rock Mark!

As for the Olight Osight. I may give one a try As needing Parelex Lens due to a nasty fall at work has made using iron sights a problem I am quickly switching to red dot optic's on everything So a reasonably priced sight would be nice

Your old man lol 😆 😂 😅 I guess we are all heading that way giving off super dad vibes lol

The sight is on sale at the Olight website for $40 off right now, so its $159.99

I think it’s a fun little gun… but, you really should make a barrel or two. In maybe some more extreme cartridges. Like .45/70gov or .500S&W or .50AE maybe even register it as an AOW. And make a silly short 3” 12ga. Or the ultimate would be a Serbu 40mm less lethal RN-50… RN-40?? Honestly if you made a very affordable less lethal launcher it could get some sales with LE I bet. An RN-50 with like multiple quick change barrels would be amazing!! Like a back packer version idk just a couple ideal… you should make one in a bigger pistol caliber that’s all I know! You’re so cool Mark I’ve worked in the precision machinery industry in the past. And have wanted to make my own guns for years. Your designs are always very unique! Anyway I love the show! -Justin Ps As silly as it sounds it would be amazing to see a full metal 12ga flare gun. Like the famous orange boat 12ga flare guns. But a lot stronger built to last. Maybe even make the frame good enough to AOW it and add a barrel sleeve for a conventional cartridge. Would love to see any sort of survival rifle from Serbu! A Mark Serbu AR-7 alternative would be amazing… sorry to rant 😅🙏

Make one chambered for 8ga industrial shells.

O No. LOL…

a cool thing i ran across recently and learned existed was bore lasers, essentially when you have scopes and the such theres a tool where you stick it in the end of the barrel and its a laser pointer that you can adjust your sights/scope to without needing to fire rounds through it i havent tried it on higher calibers, but it worked wonders on my Ruger 10/22

According to texas dems, mark is near single handly bring down the mexican govt. With .50 cals. Lol so stupid. Also, your shirt is frickin awesome

No mark YOURE a nice looking little unit!

Too bad you couldn’t sell a barrel kit to fit an ar receiver, for people who wanted to shoot a more powerful cartridge in a single shot configuration !

Tha righ' ɗere, From my own personal point of belief depicts certainly what I'm mildly confident would be an example of not quite being in the touch as I am told the verbal words go in order like this saying it is, nope? But $ 200. 00 for a pocket flashlight Is expensive.

Cool TZ episode. The gun is plum darn Keeler!Hope you’re having a nice Memorial Day .take care.

If ypu dnt like the osigjt..im disabked and on a fixed income..i need a sight..i been wanting a low power variabke scope for my mp 15 but i cant aford a scope that cost more than the rifle but id.like to actually. Hit things past spit distance lol...im exaggerating but ypu knkw what i mean..i got a cheapo pistol.style red dot..looks sexy like a.cqb blujean operator but its nor versitile enough to.nail a soada bottle.at 100 ir so..but i do need to get a big target to dial it in better.... I had buddies when i was ypung where we'd spent alota time and do stuff right..now that i got a wife and dogs ..they say..are you done yet you shot 4 shots lets go . 😢😢😢😢

Great content Mark very enjoyable thank you for sharing this six stars brother

Is that a 9 i may have missed tou saying but looks small for 50 obviously 😢😂😂😂

You got an SBR Stamp for that? 😂😂😂 atf freaking jerks.

better put some weight on that lead sled, the 9mm has too much power

gun and red dot both hella cool

One step closer to Boba Fett's EE-3 blaster.

WE WANNA SEE THE 30MM RIFLE MARK!!!!

mork subaru!

😂😂😂😂😂😂

Now make me one in 50bmg with a pistol brace and a forward grip so it's a "firearm".

Liberator?

Mark, for this application, make the cap and breech threads interrupted, for faster reloading.

I was thinking about how professional this guy has gotten, then watch him shoot across his shop testing his new toys 😂 impeccable.

That other black thing is the charger...its wireless it slips over the optic andit is the charger

Serbu, use a socket wrench to unscrew the cap/breech?

Pistol rn50 before gta6

Read the damn instructions

Non replaceable battery, no thanks. Eventually the battery will die and then it's a useless piece of glass.

What's the msrp on that hotrod?

When does Kentucky ballistics get one?

the Olight Osight is the best buy for a pistol red dot

I still drool seeing the serbu shorty 12..someday... do you ever think of making one to be a aow like a shockwave..i knkw uts.nkt as short but people would buy em
