I need to come up with a 3d printed magwell for a DPMS .308 AR that is specifically cut to hold the lever on a Magpul D50 down. I have made them for an AR15 and a 9mmPCC, but I am having issues finding anything useful, and I am not good enough at CAD to make my own. Help?

Still breaking targets at 3 gun matches...LOL

Its hilarious that they offer financing next to the "add to cart" button... or maybe not really.

Ok, This is resurrecting an 8 year old thread, but I will try to help. I assume that @Brickdude also has a Bushmaster ORC in 308, found my thread via a search, then joined just to reply. In my experience, I have not found any incompatibilities in .308 extractors. In the ORC in this thread, I currently have an APCustom extractor in my stock bolt. and it fits perfectly. That doesent do you much good, because AP is also out of bizznas. But Wilson Combat still makes and sells .308 extractors and they are even available on ebay as of this posting: Wilson .308 extractor Some guys double o-ring their extractor, but I personally don't because it pretty much guarantees if the rim fails, it takes such a big bite that you have to pound the brass out with a rod. With a single, it's not quite as aggressive and you can still get in there with a little hook and pull it out if you need to.

Hey guys, I have a 20" DPMS Classic .308 and I decided I wanted to replace the monstrously thick front sight with a skinnier one to allow for more precision. I noticed it looked rather tall, so when I had the option of what front sight post to order, I ordered the longer of the 2 choices. When the sight post arrived and I installed it, I noticed that even the longer of the 2 options was shorter than I was removing. I went ahead and installed it but I didn't like how far up it was sticking [the original was above the ears on the FSB] and I also did not like seeing daylight under the base of the front sight post or the tenuous detent positioning, so I went ahead and screwed it in to a more proper mounting depth, and now I have to work out where to aim, etc. Logically, I should be able to aim low [6 oclock hold] on close targets and be able to dead hold on farther targets without having to adjust my rear sight, but I don't know how close this is going to be in reality, and events have conspired to keep me from going to the range to positively verify any of my assumptions, so I figured I can't have been the first to have ever had this problem, so here I am. I remember hearing service rifle shooters talk about filing their front sight down to allow a 6oclock hold when it was already bottomed out, but I confess I didn't pay much attention at the time. Right now my load is a 155gr Amax at 2800fps. My targets are 90% going to be the MGM flashers out to 5-600 and those skinny little mini-poppers out to maybe half that. I would like some guidance and guestimation on my holds, sight picture and trajectory so when I do make it to the range I am at least on paper and don't look like a total douche.

Well, I did say 18"+... I don't think 20" would be out of line, but much more and we are adding weight without much benefit, since the longest I could shoot this at is 600 and that's only rarely. As far as the .260 Rem, that looks like a cool cartridge, but I am scared to get into a cartridge that I don't already load for, given the current market for reloading supplies. Plus, I don't think .260 is allowed in any heavy metal class, optics or irons..

Yup. That's why I need an 18"+ barrel... Right now it's somewhat of a one-off, although I believe my buddy [the manufacturer] is eventually going to start making them for sale. [since this isn't an official product, I'm not sure what I am or am not supposed to say about it so I am going to err on the side of caution and say as little as possible, other than the length]

So, here I am, minding my own business and I get ambushed and end up with a 17" free float tube and adapter for a DPMS pattern 308 upper... without anything to put it on. So, I have decided that this is the perfect justification to put together or purchase another upper. My problem is I am having a devil of a time deciding what I want. On one hand, it would be nice to put together a top notch, long and heavy, super accuracy rig, but I am self aware enough to know that after the new car smell wore off, it would sit in the safe and never get shot until I got tired of it and sold it for a loss. I have 16" and 20" DPMS 308's already that I use for 3 gun [and apparently the 20" might be service rifle legal, I am told] but they are both iron sighted guns. What I don't have is a scoped upper, something I could dabble in Tac Heavy Optics if I was of a mind. There's a ton of stuff for sale, even if I restrict myself to the classifieds, and that is my real problem, too many choices. Requirements: 18" minimum barrel, 20" if I am going to use a Brake like JP or SJC. Flat top upper, Prefer normal height rather than extended so I can use a 1pc mount. I don't need a forward assist, and I am on the fence about the shell deflector. Would prefer to have a complete bolt/carrier. So, 308AR, help me make up my mind what I want. Do I want to build or buy and re-configure? It would be nice if I could buy a barrel [with block and tube], upper and bolt /BC all at once as a one stop shop [to avoid buying the wrong parts, etc] without having to buy a complete upper that I am immediately going to have to disassemble. So, please, make recommendations, but tell me why I want what you are suggesting. I am looking for ideas, something to help me narrow my search.

What version of Internet Explorer are you using? If your computer recently applied updates, [The middle of last week, IIRC], you may need to turn on compatibility mode, clear your browser cache, and restart your browser to get the CCP back. Or just use Chrome.

But certainly, I can make something work, can't I? it seems I just figure out how tall the parts are and adjust with shims or Dremel, right?

So, how do I figure out the center to drill it? And what do I need to know to drill CF??

Ok, I was about to pull the trigger on the Lancer and I noticed this on their site: This means I get to instantly void my warranty and learn how to drill CF and figure out how to match up Front Sights, yes?

Ok, breath(s) taken. Easy stuff first, I already have a SJC titan comp on it, so that end of the barrel is squared away. Or rather, I HAD a SJC titan comp on it until LGS decided to stick a screwdriver through it to remove it instead of grabbing the wrench that was right there on the bench.. [sorry, Traumatic events take a moment to fade.] I also already have a couple of Magpul stocks to swap out [MOE and a ACS] depending on weather I want to carry a battery. I also already have a match trigger in it. it's not a Geiselle but it will work, and it's not on backorder, it's in the gun.. ;-) I am going to look at that lancer, it might be the ticket. [HOLY CRAP, $350 AND a month's wait??? This better be the hottest thing since Jessica Alba] Anyone happen to have a used one laying around? Then I have to come up with some sights. With 3 different DPMS rail heights [miner is the new short] that ought to be interesting.. I never thought about an adjustable gas system, but I love the one on my FAL, so that might be something...

So, I mentioned my plan to my LGS, and he says, "Come on over, we got you covered." I said "Really?" "Oh yeah, no problem, come over after work, and we will hook you up." So, over I go, after work, to be hooked up... Disassembly went about like you would expect, with much pounding and cussing and gnashing of teeth, then was heard the utterance: "OH." This was not a good sound. "Wow, that's ALOT bigger than I thought." That was a worse sound. So we march in from the shop to look at the available parts..."Nope, nope, nope, nope and nope." Friends, romans and fellow wrench turners, I have completed the walk of shame, with a bag full of rifle parts and shattered dreams. My plan not to jack with the gas-block - Gone! So, this has gone from a rescue operation to a salvage operation. I have no words for the despair in my heart right now...

Ok, guys I have another of my "why would you want to do that" questions for y'all. I have a 308 Bushmanster ORC that I want to convert to an iron sight gun. In normal times, I might just sell it and buy the gun I want, but I haven't seen the exact configuration I want for sale anywhere, even before the panic. So I think my best option is to change what I have to what I want. My first and most pressing question is what to do about a free float tube. When I search on 308 free float tubes for Bushmaster I get some conflicting information on what will fit, and whether a standard AR tube will fit or if I need a special adapter. My gun looks exactly like this, except I have MOE hand guards on it. Since I was able to replace the hand guards with standard AR furniture, it stands to reason the mounting for free float tubes might also be the same. If I understand the difference, I only have to worry about the odd size free float tube/adapter if my rifle came with a FF tube from the factory, which mine did not. What I think I want is to run a free float out to the brake, and use a standard AR fixed Rear sight. Where I am on the fence is with the front sight. First option is to clamp a normal front sight [or a folding one] to the barrel, butted up against the back of the brake, and stop the free float tube just before it. I want to clamp because I don't want to mill for pins and I am not going to jack with the gas system. My objective is to get the longest sight radius I can. Second option is to go with a longer tube, and attach the FS to the tube. This has the advantage of seeming simpler but since the front sight is going to take some abuse [this s going to be a 3 gun rifle] going into barricades and dump barrels I would want to be sure it was going to stay put. It seems clamped to the barrel might be strongest and most durable, but the least elegant, and in the way if I decide to clamp on a scope for load testing. A folding clamp on like an ARMS #41 or the YHM 9394 would solve the "in the way" part but be less durable. The unknown [by me] is where a free float mounted front sight fits in. If it makes a difference I am considering an AP Carbon fiber tube to save some weight.
