The "head" on the buffer could still lose some weight. I'm thinking you could drill / mill out some speed holes perpendicular to the length of the thing...Just go all the way through for a matching hole on the opposite side.

finally started adding bbl data to the PW Database. It'll take a few days to get all the fields filled out, but it's coming along. Data includes length, gas block size, chrome lined/not, bbl material, gas system length, twist, rifling method, fluted, and chamber spec. Starting to come together. After this, the real monumental task (doing the same kind of thing for the rails tab!) is next. whoa nelly, that's gonna take awhile.

I'm finally ready for an optic or sights for my ultra light build.
Took off my RMR with larue mount. I have looked at the spread sheet and have a couple questions. The shield rds leads the way at 0.5oz but how much do the risers and mount weigh? I have never heard of the MFT folding sights, any cons to them? Pros? I thought I was good on getting the bobro low riders at 1.7oz for the pair but if there is a lighter and good alternative I am all ears. I am trying to get the gun in at 3.5lbs with optics. Almost there |

Can't wait to see your data on the shield parts, especially the mount, which sounds kinda hokey. Stacked polymer mounts? If they hold zero, it's all good, I just wish they had a mount that was designed from the ground up to work with AR type guns. The RMS is still the direction I plan to go. Hella light.

Feel dumb for not weighing it before but it should be relatively the same. Also i noticed on the spreadsheet that the PSA full auto carrier is listed as 11.55oz. Mine is a premium with the chrome lining and its weighing 329 grams 11.60oz. Should we change it or is it close enough? |
|

google says that 329g is 11.6051. I've got 3 digits to work with on the sheet format, so I'll update it to 11.605 for the PSA Premium. The non-premium variant may have a different weight, and we've had a separate listing for it since the database started.
YW for the spreadsheet BTW. It has been a lot of work, but I have an OCD issue that makes it satisfying....once a section is 'done', and highly irritating when it's not, so I'm compelled to keep after it. |

.05 ounces is within the margin of error for most scales.

I did say I was chasing grams but I chose the kmr because of its capabilities and lightweight.
I have to agree that that carbon weave one is very ugly. In my previous post about this build I have always stated it will be on metal receivers and be functional so that it would allow me to add things later if needed. Plus I want it to look good too. With my 9" kmr, titanium hardware and hopefully an aluminum barrel but I will be pretty close to the weight of the carbon braided one. Thanks for all the input. I have been following this thread very closely. I have a few parts coming in this week and will finalize my lower. |

Has anyone noticed the intro page for Master of Arms on Vertex ops website? ".....Lightweight 7075 Aluminum receivers and EVEN LIGHTER STRONGER 7095 Tennalum Upper and Lower Receivers." I went ahead and emailed Vertex ops, and they said... IT IS NOT A TYPO. THEY ARE COMING! (I hope I can share this info here) Further email exchange with Master of Arms revealed that the new 7095 Tennalum receivers will be very much lighter than their current Esoteric set. Of course, the Tennalum receivers will be more costly....maybe around what V7 charged for their 2055 set. I am guessing the Tennalum set will maintain the same form factor of their Esoteric set: No forward assist and no port door. Really pumped for this! What do you guys think? |

View Quote It will be very similar to the esoteric. I believe they will be called arcane and have been working on getting it out for a while. Some of us have known this for a while. I think there was a flyer they sent out a while back before they relaunched their new website that talked about this. Remember, Master of Arms is the same as Next Intent Tactical but rebranded. In fact, I like what they're doing by coming out with these new lightweight products. They have found our niche and are rolling with it like V7. Tennalum is the alloy that V7 has used for their Ultra Light Castle Night. It's actually much more expensive than 7075 and is much harder to machine. I believe I read somewhere that it is roughly 35 percent stronger weight to strength than 7075. That puts it in the strength realm of Grade 5 Ti. It's also much harder to come by and find. I'm hoping that MoA actually makes a carrier out of tennalum. Tennalum was actually designed specifically for the defense industry but hasn't really kicked off yet, with it's superior strength and corrosion resistance over 7075. Props to them. I can't wait for the new Ti adjustable carrier among their new arcane receiver set. Also did you guys see that the esoteric upper has a roll pin so the charging handle doesn't ruin the receiver when it interfaces? Pretty neat. All-in-all I really hope they deliver a superior product with their new name. I hope other companies start doing the tennalum thing as well. |

View Quote Looking closely at their website it also states that the front rail section on some of their rails is not included in price or weight. Unless you buy the atlas version which is already heavier than the kmr. It also states that you cannot run BUIS on their front rail section. I'm thinking it has something to do with the height it sits at. So if my numbers are correct my 9" kmr with titanium hardware comes in at 5.25oz. With a aluminum barrel nut it should be between 4.8-5.0 oz. The 9" brigand comes it at 3.9oz and if I add their rail section it will be 4.5 oz and not able to host a front sight I also have some custom rail work planned for it that should drop in a few grams (I actually have no idea how much it will save. It will be experimental weight savings as well as aesthetics to match the balios lite upper). So yes the brigand does come in a few tenths lighter but also not able to host iron sights |

I got mine from a guy named Anibal out of Texas in 2014. Good guy, and member here, but he hasn't been around for a good minute. Last time he posted was mid-2016, but I emailed him a few days ago. So far, no response. I bought two for $70 each. Ended up selling one, and the other is mounted on a BCM, behind a pinned 14.5" barrel. Joel at V7 had a few (literally, one or two) prototypes in aluminum floating around in 2014, but he sold them to customers who heard about them. If enough people inquired, he might turn a few, but I doubt it. He hasn't released any new products in quite some time, and it looks like the bulk of his focus is on those gaudy receivers he's manufacturing. All due, but V7 is somewhat stale these days. |

Thanks socom,
So that one you have is not coming off anytime soon huh? It was worth a shot. I will just have to be patient and hopefully someone does a run of them. I have time since I am trying to get some work done to the kmr rail anyways. I am content with finalizing my lower over the next couple days |

Am I missing something? The link you posted shows a 6.8oz receiver out of 7075.

Not a huge fan of V7 receivers, but Battle Arms and 2A Arms are arguably the best looking sets on the market with the edge going to 2A simply because they manufacture matching rails. |

Yeah it's hard to compare apples to apples in this line of work with so many variations of rails. Picatinny, keymod, m-lok, tubes etc etc
I added the comment of adding the front rail because I am running irons. So I wanted to compare rails that could host a front iron sight. |
