I weighed a Magpul MOE polymer trigger gaurd at 5 grams (.176 oz) I put a B5 composite on the scale and it also came in at 5 grams. Both weighed the same with or without the roll pin so I'd say they are both in the same weight range.
My scale is not that great, it's finest measurement is whole grams so I'm not going to claim these as "U" weights, I'll wait until someone comes along with a better scale. That roll pin must not weigh much! The B5 did not come with a roll pin, just a set screw. I do like the finish of the B5 better though. It has a smooth finish as opposed to the grainy texture of the MOE if that matters to you. It looks closer to the finish on the receiver. |

|
my "big scale" isn't that accurate, but I have a small one that is hella accurate. Down to thousandths of an oz. It'll work for the B5. It's kind of annoying that their www site is so far off base with its measurement. Anyone with the ability to make lots of gun parts has a decent scale laying around and could publish good data. Oh well, this is EXACTLY why we have "U" data. It really is what separates the PWD from lots of lots of google searches.

Anyone have experience with fostech upper receiver, if so are they durable. And where the hell can you find one. I was looking at parts list and went to search and can't seem to find one anywhere

if you go to FTW Coatings facebook page, they say on there that they have them....but I don't see any way to order on their www site. It may be a call-in-order-only kind of situation. I think you may have to buy the upper/lower as a set as well...not 100% sure on that. I FB msg'd them a question to clarify how exactly you get these and will post up any response I get.
PWD update: the stock section will be done today. Took longer than expected but that is water under the bridge now. Probably work on barrels next. I'd like to add 4-5 more brands to the bbl section. I know there are a lot more options 'out there' than what the PWD currently has.... |

The only durability thing i would advise with the uppers is don't use a ridiculously heavy 20"+ bull barrel and slam the upper open, or put too much torque on the barrel nut, etc. They are about as tough as 6061 aluminum, it's plenty tough but it isn't 7075. Just keep that in mind. View Quote |

I just want to know is fostech really did perfect the casting process. IIRC, some of the examples of magtec failure showed small voids scattered throughout the casting. Not good.

***** UPDATE******
I just got off the phone with FTW coatings. They have 4 stripped fostech magnesium uppers in stock. The gentleman on the phone (forgive me but I forgot his name) was very nice and helpful. He explained to me that he is good friends with the owner of fostech and was given a few of the uppers in the raw. That's why he has some to sell. He assured me that fostech was planning on releasing some time soon but unknown exactly. I paid $120 shipped with my choice of ceracote color. He was wondering how and why there was a sudden interest in these and I told him about this thread and that he will probably sell out before the end of the day as soon as I post this. Happy hunting |

Hey everyone, been following this thread for quite some time now and figured I'd finally join the conversation. Just want to thank everyone for doing the work and posting weights. I've went through all 49 pages of this forum and the awesome spreadsheet to come up with a build. I'm working with Witt Machine now to build an integrally suppressed 300 BLK upper. Here's the part list that I've got going so far, the barrel and the suppressor I left to Witt Machine to handle.
Upper Parts: Fostech Fighter Lite Upper Receiver Whiskey Arms Aluminum Carrier + Key JP Enhanced Bolt Assembly Group Brigand Arms 15'' Edge Handguard with Barrel Nut Anderson Manufacturing Charging Handle Lower Parts: Tegra Arms Lower New Frontier Arm LPK Stock (to be determined) All in all, maybe a sub 5 pound integrally suppressed rifle? Probably won't find out for another year since it's a NFA item... Anyways, I was the one who posted about the Fostech Fighter Lite upper on the spreadsheet. I found out about it after FTW Coatings was trying to sell the full set on gunbrokers but since I just wanted the upper, I called in and chatted with Ryan Cheney. He sold me an upper for $126 shipped priority mail and kerakoted in my color preference. I had it shipped directly to Witt Machine so I haven't seen it or gotten a weight confirmation but for those that have ordered it, post pics and weights when you get the chance! :D |
|
|
This is great. I don't think fostech realizes how many they could be on the verge of selling after this discussion. Keep us up to date when you guys get these. My only thing holding me back is confirmation of durability, but cost is fantastic being the lightest weight out there it appears.
|
|

Is there a way to independently test these things? Like MPI? Isn't that how they find voids in bolt steel? Not sure if that'd work on Mg, but there has to be some technique for inspecting that...right? They are hella light and inexpensive, which is a hell of a combo!
@skinnywill welcome to the sickness. PWD update: added a bunch of gas block and muzzle device data that Brownells helped me get. Had a big catalog I was going to get rid of that was a couple years old. Then I noticed that they actually have some weight / other data for certain kinds of parts. It was kinda random, but like I said they had lots of GB and muzzle stuff. Anyway, info added. :) |

I got a new product alert. Cryptic coatings lightweight bolt carrier group. It's the lightest steel carrier now. The finish on these are fantastic BTW, it really is as good as they say, and definitely worth the $. I was running one of their mystic black 308 carriers in a build for a long time, I didn't realize the rifle was undergassed until i tried a nitrided bolt carrier, lol. Then it was short stroke city!!! Rifle length gas on a 16 in barrel is a terrible idea BTW. The bolt carrier group weighs 8.2 oz, that's with the bolt and everything. http://www.crypticcoatings.com/lightweight-bolt-carrier-group/

On the note of bcg. Has anyone had experience with right to bear arms lightweight bcg. It is same as aim surplus at 8.9oz complete but they sell the carrier by itself which is currently $65.

Going off memory, but the mag lowers were nickel plated and then duracoated. They later switched to Cerakote. The Cerakote was better but still not great likely due to the nickel plating underneath it. I believe that was the same process BCM used with the KMR. And in all likelihood is the same thing fostech is doing.

Still looking for data on V7's Inconel gas tube. Asked Joel about it over a year ago, and he simply said that it weighs a smidgeon more than a standard one.
Anyone ever weighed one? |

Was messing around in the PWD the other day and noticed you had the Geissele SD3G listed without a weight. Today I went through the frustrating process of taking out the FCG, safety etc, without any punches or a vice or any kind of proper workspace where I am right now and weighed the whole thing to give you my data.
i just opened it back up to update the weight and noticed it's listed twice, once with a weight and once without. Time to put my lower back together. grumble grumble |

Apparently the boys at B5 don't own a decent scale, which makes me suspect there accuracy of any other weight data, though I suppose we are only talking about a 5/100th oz difference.

Was looking through the PWD after hearing about the Cryptic LW BCG and saw some stuff has been errantly changed.
- The Cryptic LW carrier is listed as 8.2oz on the manufacturer's website with only the mystic black coating available. PWD has it at 8.8 and 8.818 with two different coatings. - 2A Armament has a model listed as "U-LW Ti, adjustable gas key". They make no such model. Additionally, I know their models (a full mass, a LW with steel/aluminum, and a regulated LW steel/aluminum) used to be listed, because I used the PWD to shop for mine. - Ballistic Advantage does not make a titanium BCG. Two are listed by them. - CMMG is listed as producing the Gunner Lightweight BCG. That's a Faxon product. I didn't make any corrections as it appears someone has messed with the sorting on the manufacturers, but the number of products has also changed. Just wanted to bring it to someone's attention. |
|
|
Thanks for bringing this up. I just backed it up a couple days ago so it shouldn't be hard to cut/paste the BCG section. Hopefully it's the only section with issues....

You can protect data that already entered in sheets. From editing and sorting I believe. Just leave space for people to add and you can re sort the data at your own will.

The idea has been suggested before. Reluctantly, I suppose it might be the way to go. If anything ever happens to me, someone else could always make their own copy of the data and keep the PWD going, I suppose. Hmm. Guess I'll add the "submit user data" page today and lock the rest down, once I figure out the extent of the corruption and repair it...

Once you figure out what needs to be fixed and get it corrected, you should be able to lock everything down except the user weights and possibly the comments/notes column. People don't need to be able to sort the data in the PWD - they can C+P if they want that functionality (or save their own copy). Leave a last page open for new product submissions that you can periodically clear out and add yourself.
Open source info is great until you remember how stupid the average person is and that half the people out there are worse than average. |
