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.

[@DisgustedGenXr]

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

[@liggerstuxin1]

Seems common sense but not for some

[@austinclements8010]

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

[@gullreefclub]

I purchased my first one of those about 35 years ago and along with scope ring torque wrench and levels that mount on my scope or 1913 picatiny rail.

[@justinspringstun5836]

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 😅🙏

[@josephcormier5974]

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

[@frankyg2384]

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.

[@Powershift]

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

[@d3athreaper100]

This would destroy a suppressor im assuming. Thats ALOT of unburnt powder

[@kompound52]

​@d3athreaper100 it's 9mm, plenty of barrel there to burn that powder.

[@ZURAD]

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.

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

[@markserbu]

@Jesses001 That's certainly a roundabout way of calling me the word that generally precedes "savant"! :-D I'm pretty sure I have a bit of both idiot and savant, but that's not usually what's at play in my KZbin videos. There's a certain stress involved with speaking off-the-cuff when the camera is rolling, especially for me. Many times I correct my mistakes with text on the screen, and some of the bigger mistakes just get edited out altogether. But some of the mistakes I just leave in because sometimes the controversy over the "wrong answer" can be good.

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?

[@krinkov39]

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.

[@MarkSerbusOtherGunChannel]

@krinkov39 Sorry, but your comment is dumb on at least a few levels. First, I've made TWO .50 BMG firearms with 10" barrels, but I registered them as NFA short-barreled riles so there'd be no question that they actually were NOT pistols. Second, there have been many .50 BMG pistols made and transferred through the years. The first one was at least 20 years ago. "No one has sold a .50 BMG pistol yet so it's still legal." How the hell do you know that? You obviously don't, because I know it's not true. So you bolstered your weak, dumb case with a lie. Nice. Third, ATF doesn't necessarily ban armor-piercing ammo because it fits in a handgun. Note the case of SS-109 ammunition. Have a nice night.
