BOHICA no longer selling .510 DTC uppers

[Mechified]

1. Yes, I am a gunsmith & I happen to own the same Bohica MKIII that we are talking about 2. I had several conversations with Chris (the owner of Bohica) about the situation and what transpired during & since the "KB" 3. I was in contact with a family member of the kid who had the "KB" 4. Both Chris (Bohica) and myself conducted several tests to try to duplicate the "KB" (in a controlled, safe way, of course) and I was the only one , to my knowledge, who was able to detonate a primed case in the chamber before the bolt was in battery. Guess how I found the method that worked???? (Hint: I looked one last time at the pics & discovered the hammer pin was absent from its seat on the right side of the receiver!) Just the force from the bolt being closed normally caused the hammer to fall immediately before the bolt went into battery. All I had to do from the start was just look at the pics CLOSELY. Again, you should have done the same, unless, of course, you don't know (or have any personal experience with) 50 caliber AR-15 uppers & their inner-workings

Wow, nasty... Is the kid OK?

[tdaughg]

guess its a good thing i used kns pins instead of the std ones. no real issues with them working there way out.

2 more for you

Well, I found out the hard way: going to the range with my unfired .50, excited like a kid on Xmas morning.& With me were about 40 lovingly, painstakingly assembled rounds of DTC created by my own hands. After probably a dozen or so "CLICK"'s (not the big "BOOM" I was looking for) I gave up. After chatting with my bros on FCSA forum, I had found that I didn't "arm" my CCI #35's. With these 50BMG primers, they need to be pushed HARD into the primer pocket until they are, in essence "flat' (meaning that you can no longer see the radius on each primer's circumference). So, I literally had to "disassemble" ALL FORTY of my cartridges (pull the bullet, dump the propellant) and put the primed cases back up on top of my press and "smash" the primer (with a good "humph!") flat into the pocket. Reassembly of rounds followed, and the next day at the range was all about "SON-OF-A-B***H!!!!!! I went through ALL 40 of those rounds ALREADY???" ........but the smile was still on my face: shooting a 50 is light years beyond the fun & exhilaration you get when shooting any firearm @ your local range! Anyway, I hope that answered your question. Priming (AND loading) for the "big fifty" is a whole different game than for any other firearm cartridge!

My MKIII with newly-fitted recoil pad, target grip & ArmaLite AR-50 Brake. LUUUUUVE at first fire!

How does the AR50 brake compare to the standard BOHICA brake on the MKIII?

Where did u find your recoil pad?
I ended up taking the the whole back plate off of my M.P. PRS stock, and
machining a new one to take a mossberg limbsaver pad.... apparently I am a research-tard as well as a post-tard.....

who makes a .510 upper in the same price range as the bohica? any mag fed?

nobody else is in the same price range as Bohica. Basically, nobody else is under $1750 for a basic upper, and yes, there are mag-fed bolt-action uppers available.

Primer Arming

Thanks for the info, now I need to go check all the ammo I loaded last night.

which ones are mag fed?

which ones are mag fed?

IIRC, it is State Arms, and it is a "side-feed" 5-round mag. BUT: the only problem is (and I know because I called the company to order one) they are "no longer making any more rifles chambered in 50DTC. 50BMG ONLY. Sorry to break it to you. There's always ALS & Ferrett, I believe, but they are single-shot as well. BTW, I read a review on that mag-fed one and it said that the magazine was "difficult to install/seat & feeding problems occurred due to the mag." IMO, you could load/fire/unload/reload/fire just as quick with a single shot in these kind of rifles. But that's just me.

EDIT: the mag-fed one I was referring to as being discontinued is the SHTF50 by Safety Harbor.

Who cares? If you plan on needing a quick follow up shot with you a 50, you probably are either a mall ninja or you just need more practise shooting. I've seen 5 shots fired from a shell holder action (completely remove the bolt, remove brass, place new round in bolt, reinsert bolt into rifle, close bolt, aim and fire) in less than 38 seconds which set a world record group of 2.608". If you need to shoot faster than that, you are one of a very few people who do. Besides, once you cut away enough of the receiver to fit a magazine in, you've obviously made the receiver less ridgid than if it were a single shot. So, do you really want to give up some of the precission that an action is capable of just to have a needless magazine?

Wow. Nice flame, dude. It has nothing to do with followup. Every rifle I own is magazine fed, and I'd just like to keep it that way, if it's alright with you. With your logic I may as well go back to cap and ball. Who needs to shoot more than one round every five minutes! Who NEEDS to!

Sounds like something an anti would say.

I took my first buck with a second shot from a front stuffer. My ramrod broke while I was reloading and I still was able to reload in about one minute, dump out the broken pieces of ramrod and get a second shot off.

I really don't think I was flaming you. I was pointing out that one's perceived need for a magazine can be easily changed once one finds out that they will be limiting their choices and sacraficing a little precission just for a magazine. Before I bought my first 50, I thought the same way that you are thinking now. I'm glad that I saw the light before making a huge investment into something that I would not be happy with today. If you think that my information is too anti-gun for you, just ignore it.

BTW, tomorrow would be a good day for you to go to Angeles and see a selection of 50s. I'd go there just to let you shoot both of mine but, they are not mag fed.

[supersonic]

I agree with CSA in that the mag-fed version I saw (the now-unavailable *DTC* SHTF50) looks like there is almost no receiver left when the mag is out and bolt is open. WAAAAY too much potential for structural failure, if you ask me. As far as I know, if you want a Mag-Fed 50, you will either have to already own a RAW lower (for the 50BMG), or go with .338LM/.416Barrett. None are available in DTC that I can see.
