are there any sales on the mag tac lowers. Brownells does have blacks for $80, PSA for $90... But damn, where are those ones for $54...
I know the receivers are not terribly strong, but I'll be putting a law foldier on the back anyway, so if I fall on the gun, it will fail at one point or another back there anway. |

Just an FYI, there is a whole discussion on another forum about titanium needing special equipment to weld it properly and whether or not the places that pin comps and brakes are equiped to pin a titanium muzzle device. For those going 14.5" and pinned it may matter, if it's a real concern at all. |

This is mildly disappointing. I was hoping it would be significantly lighter than anything else on the market. Instead it's a tenth or two of an ounce lighter. It seems like none of the current companies truly understand lightweight. They get a few parts there, a few more parts almost there, and completely miss the mark with other parts. |

I would like V7 to make a Ti barrel nut for the KMR and maybe change the steel hardware on the Seekins T-1 mount to Ti...
I think they are doing well finding little niches to make light wt parts in.... The Boomfab seems to have found a major way to save some weight. (this looks to be the light weight fanatic's bolt carrier of choice so far) It will be interesting to see how this light wt trend will progress over the next year |

I figure if I've got the forward assist I might as well have a BCG that can use it so that rules out the JP carriers. Youngs looks OK but the website looks pretty janky and its quite expensive. Any other options? I'd really like a lightweight and N/B carrier for my light build.
And yes! Looking forward to how V7 can really optimize the weight on every possible part. I'm a huge fan of the excellent quality and good service. |

Youngs is anything but janky. They are GTG. I have their super lite carrier in two ARs and they are nice. Only slightly heavier than a JP and has FA notches.

Silver solder should work. all I know, is that if the ATF can put the barrel in a vise and turn off the muzzle deivce w/ a 3 foot pipe wrence w/o destroying the muzzle threads in the process they will have the DA prosecute you. So, SS might work technically, but I don't know if you would be GTG legally. |

Gotcha. They redid their website recently so all old links on old threads are garbage. As for their products, they are some of the best out there.

OP, a big oversight is the V7 "basic" upper receiver, sans F/A or accomidations for a port door. It is claimed at 6.4 oz. Please add to the op.
http://www.v7weaponsystems.com/collections/frontpage/products/v7-ar-15-basic-upper-receiver Also, I see the boomfab carrier isn't in the OP:

I spoke with Joel, of V7, a few weeks ago by email about light weight bolt carrier options coming out of their shop. In short he feels that the original M16 weight carrier with standard gas key and a standard gas block is the most reliable option out there. Joel also indicated that V7 will not be offering a light weight bcg because he feels it's better to have a little extra weight and no reliablity issues vs having a light weight bcg that must be tuned with an adjustable gas block or gas key.
In my opinion Joel still sees a gun, even one used for competitive shooting, as a tool that could end up in a life or death situation and he prefers to err on the side of reliablity over weight savings. I appreciate that philosophy Email Joel youself if you want more info as I may have not conveyed his comments exactly as he intended. Wes |

They did prosecute a guy once for SBR violtion b/c they broke his soldered flash hider loose w/ a big pipe wrence  This is why shops do the blind pin'n weld. To remove the FH you either have to destroy it or muzzle...
Yeah, I went ahead and ordered theJP carrier. I couldn't wait for spikes any longer and w/ steel, you don't heave to worry about wear at the cam pin area or whatever. Also, heavy weight carriers are dildos, they are only an unimaginative way to slow down the cyclic rate of an overgassed rack rifle. I was talking to a guy who said "well if you round is bent or dirty in combat, a LW carrier might not be able to drive it into battery  Lol, bro, if you are trying to chambered damaged cartridges w/ pebbles on them, you may as well shoot youself in the leg and surrender.  W/ stupidity like this, there is no wonder the F/A exists.

With a big three foot pipe wrench, and a good barrel vise that is as tight as you can make the thing without breaking the vise. One could shear that little steel pin off pretty easily, and without very much force!
In that way of thinking, I would say anyone with a pinned, and welded muzzle device is pretty well fucked if they're ever questioned... |

The arguemnt about the pinweld job is that it destroys the threads, but yes, the distinction is arbitrary. |

I recently bought a Bravo Company 16" ELW stripped barrel and it weighs in at 22.8 oz, my scale is accurate to +/-0.1 oz.
Some other items I weighed too: Mid Length Gas Tube 0.8 oz SLR Sentry Clamp On 0.625" GB 1.2 oz SLR 13" Lite Rail (9.1 oz w/o Barrel Nut) (1.1 oz for the Barrel Nut) Upper Receiver (w/ FA and Door) 8.4 oz Spikes Full Auto BCG 11.6 oz BCM Gunfighter CH 1.3 oz Trijicon MS03 Red Dot mounted on JP Enterprises mount (JPA-WPG) - total 2.7 oz YHM 3 slot 1/2" rail riser 1.1 oz Also, because of the adjustable gas block, I ditched the counter weights in the carbine buffer, the the empty carbine buffer weighs 1.1 oz and the weights came in at 1.9 oz. This build weighs in a 5.97 lbs unloaded! |

Before you step up on your soap box of holy AR15 highness and comment on a manufactures capability, experience and knowledge, how about contacting the company directly, as I suggested, and getting more info.

I've read your posts and asked you questions in a few threads to get information from you about what you've been using. I know you know what you are talking about and I also know what I'm talking about. I do my best to make sure I fully understand what I'm talking about before I post. That said...

Your one liner comment conveys that the owner of V7 Weapon Systems doesn't know he is talking about when it comes to BCG. I'm simply suggesting you consider speaking directly to the man yourself before you make a similar statement so that you fully understand what he knows and why he made a business decision to not offer a niche market product that can have some install requirements that are beyond "install the part and start shooting".

Great thread! Glad I found it. I'm looking to loose some weight. It's not going to be a 5lb deal since I will be using an AAC suppressor (damn heavy ass muzzle devices). But I think I can drop a good amount of weight with options here without sacrificing reliability and accuracy.
I'm undecided about a lightweight slab side upper though. Doing some googling and site searching seemed to indicate that the FA does serve a worthwhile purpose. Am I wrong there? I'm a little hesitant about a Mag Tac upper given stresses (maybe I'm wrong there too). I will be getting one of their lowers though. Also, PursuitSS seemed to indicate it is possible to go with a lower BCG without sacrificing reliability. Can someone clue me in on that? I don't understand how that's possible. |
AK and 1911 belong in the trash can. AR15 and Glock belong in recycling bin. VZ58 and CZ75 belong in your hands.

I don't understand how that's possible. a gun wuth less reciptocating mass can be absolutely reliable provided that the gas system is moderated as merely lightening the reciprocating mass will lead to q higher cyclic rate which can be a factor in various types of stoppages. i will say though that having a low mass system may be eating into the margins. a massive and slow group will probably have more margin with a wider vareity of ammo than a low mass group. of course, a low mass group can have more versatility if the gas block is selectable, but then you are introducing more complexity and hence opportunity for operator error into the equation. for commonly used rack rifles, or standard issue service weapons, some of which are used by people who woulld absolutely know nothing about guns were they not LEO, it is hard to beat the 5.9 lb M4('gry) with a H buffer and auto carrier. for me, i choose a more complex and higher performing customized rifle that allowsfaster followups from compromised shooting positions. |

But at a certain point, what you can accomplish on a controlled range is more than you can accomplish in the real world, or more suitably, a gaming environment. So while thing's like ammo selection don't particularly phase me, adjusting a gas regulator on the fly may prove challenging in high pressure situations. Now am I reading this wrong or does a low mass group limit your ammo selection? And if so, what does it limit it to? To me this seems like the key consideration. Again, check me if I'm out of my lane. |
AK and 1911 belong in the trash can. AR15 and Glock belong in recycling bin. VZ58 and CZ75 belong in your hands.

V7's choice not to offer a lightweight BCG is their choice. They seem to make very good products.
My interpretation of the theme of this thread is about building the lightest, reliable AR rifles possible, not building a lightweight HD or Duty AR. I could be wrong, but that's how I use the info. I would like it if V7 wanted to offer some competition in the lightweight BCG market knowing that, but if not, I will continue to use other brands. Maybe V7 doesn't really want the liability of someone not understanding their parts and using them in an HD gun. It makes no difference to me, I just won't be using their BCGs. There are other lightweight BCGs for my lightweight builds, and there are several mil-spec BCGs that I run in my HD guns. I'm covered. |

Doing some googling and site searching seemed to indicate that the FA does serve a worthwhile purpose. Am I wrong there? I'm a little hesitant about a Mag Tac upper given stresses (maybe I'm wrong there too). I will be getting one of their lowers though. Also, PursuitSS seemed to indicate it is possible to go with a lower BCG without sacrificing reliability. Can someone clue me in on that?

Again, check me if I'm out of my lane. You are not entirely wrong, but you are missing a bit about what an adjustable gas system allows the shooter to do. For 3gun, I would adjust the gas system to the one and only one type of ammo I would be using for matchs. What I do with the rifle is a game and the only thing on the line is a prize table. Proper maintenance and pre-testing of equipment with ammo will have proofed the rifle out before using it in a match. For the Nth degree of competitiveness a lightened operating system is great. For an LEO, he would adjust the gas system to cycle the lightest load and then check function of hotter loads, or more specifically the dept issued loads. An LEO is not likely to shoot his patrol rifle in most every day patrol carry. Even a worst case scenario is at most 60rds fired. Theoretically that patrol rifle should be clean and lubed and stored in a clean case. Realistically most LEO's who are not shooters and never train with their weapons will never see a benefit to a lightened operating system or adjustable gas. These are two very different operating environments and martial skill sets. |

I just started to put together an ultralight build myself and decided to weight all the individual parts not only for this build, but from other rifles and spares i had lying around.

Note that the v7 page lists the barrel nut weight and rail weight as if they aren't totalled into the 12.6 quoted earlier. The barrel nut weighs 2.6oz(no mention of bolts required to use nuts being included or not) So you are looking at 15.2oz total for the V7 system. For the money, the Keymod and MLock line from Midwest Industries appears to be the best light weight option out there and if money is of no concern then you turn to BCM or a custom carbon fiber job.

How much does Krylon or Cerakote weigh after it dries?
