Yes didn't make sense your bolt would smash the receiver. Now I'm not sure were the 11oz weight came from. I weighed The stock without the buffer and it was 9.6. Add the buffer and spring and your up well past that. |

that could be a good way to moderate an overgassed gun, provided the set screw can be staked so it doesn't work loose. This makes a pinned chopped aluminum FSB an even better option. |

If you order the shrote version from ACE, they include teh short receiver extention that uses the carbine reciver extention, short foam tube, gusset, butt, & two rubber pads. if you order the long version, you do NOT get the receiver extention, and you get a longer foam tube. |

There is a ular that is listed that is entry length that has a short tube. IMHO if your looking at weight over function that would be the ticket. As it uses the carbine length tube. The weight of the riffle buffer almost negates any saving with stock. Unless I'm missing something now that I have the ular and minimalist set up to compare. |

Alright, I took the plunge yesterday and started ordering parts for a LW build. I realize that saving 2 - 4 ounces on as many items as possible adds up to significant weight savings. I found a DD 14.5" LW mid-length in the old .625 configuration yesterday, which started me off.
As I see it, the lightest grip available is the MOE K, which is slightly lighter than the Umbrella Model 23. Anyone got anything lighter? |

Make sure you weigh the "K" grip when you get it. Reports are that the design has been modified, and it is heavier now.

I find it aggravating that, for the most part, companies don't list the weight of their products. It is doubly frustrating when something is pitched as 'lightweigt" like barrels, yet the weight isn't posted or even available through search. If the K grip is not as light as originally posted, I may rethink it. Thanks |

So what do you guys think is the best bang for your buck? It looks to me like MagTac lowers, but I'm not sure of how durable they are, to be honest with you. That, or a lightweight BCG, but again, I am unsure about how that may negatively affect my reliability.
I'm trying to drop weight, while still retaining as much durability, reliability and function as possible. I've got a pretty light gun, as it is, but I am going to screw that up with a magnified optic, before too long.

You say you want to retain durability, which to me means a forged, or billet, receiver. The Mag Tactical is the lightest option and I almost ordered one, but I just can't do it since it is cast. That's just my opinion. I am trying the new 2A Armament set posted already in this thread. The cost is much higher than the Mag Tac. I would look at an Aero Precision upper without FA and either an Aero precision lower, or the Mag Tactical if you are OK with cast magnesium alloy. I would not be comfortable with a cast upper. |

What's the weight or approximate weight gained by adding an optic and mount? Once you figure those out, figure out what your goal weight is and weigh the options. |

I threw some parts together I had here in the shop, just to see what something like this would weigh.
2A Upper and lower (-lite) Standard FA BCG Standard CH AM-TAC 16" Mid-Length barrel 15" KRS-V2 rail Magpul furniture CTR, and MIAD Spikes new BUIS set (frickin real nice parts!) EOTECH XPS-2 7.0 lbs I think this could easily be shaped down to a 6 lb rifle using other lightweight parts listed in this thread. I was just curious what a somewhat feature rich rifle would weigh. The upper is also a pre-production belled front model. so with the production upper, this would be in the 6.x range weight wise.

I have two Mag Tactical lowers built up with a few hundred rounds fired from each of them. No issues yet but I'm not knocking doors down with them like so many others here must do. Just shooting holes in paper. I just picked up 4 more Mag Tactical lowers for $54.00 each. With occasional bargains like that, I really don't care if one ever failed for whatever reason. |

Wow, I have a Balios lite set on order, but was not thinking a weight below 5 pounds would be possible. What parts would you use to go down that light? I have ordered the following: DD .625 14.5" LW mid-length barrel (was lucky to find one) BCM Mod 1 comp (to be pinned) JP LMOS BCG BCM KMR 10" SLR .625 adjustable gas block and middy gas tube Raptor CH Aimpoint T-1 and Fortis micro (or the new Aero precision when it comes out) Ace ARUL WOA lpk Moe K or Umbrella Model 23 ALG ACT Thinking about V7 lightweight take down/pivot pins, safety, and Strike Industries dust cover. Parts should start arriving this week. |

It's no where near a "lightweight," but a lot of that weight is a Comp M4S in a Larue mount. Reason I'm perusing this thread is within the next year or so, I want to add a Vortex 1-6x with a Aero mount, at roughly 28oz, then some sort of IR laser when I get around to grabbing NVGs. General goal I'm after is keeping the rifle sub-10lbs. |

So with your current set up switching the vortex for the m4s you'll gain 19 oz putting you at 9lb 10oz. A dbal d2 is 12.5oz, that would put you at 10lbs 6.5oz. So you need to cut 6.5oz off your current build to make your 10lbs goal. More info on current set up, i.e. Barel length/profile, rail system, muzzle break, grip, butt stock, buis...and anything else I missed. Shaving 6.5 oz might be as easy as switching out you butt stock... |

My parts list:
BCM 16" LW middy BCM bolt BCM 13" KMR BCM Gunfighter grip MOD 1 SLR Sentry 6 gas block Rainier Raptor CH PWS FCS556 Spikes melonite gas tube RRA chrome bolt carrier - semi - 8 3/8 oz.. Geissele S3G trigger Ace ARFX stock - rifle buffer, and spring to accommodate the mid-length gas system for recoil purposes. Aero Precision NO FA upper Del-Ton lower All this comes out to 5lbs. 13oz. without optics, or BUIS. With a Comp 3, and a 20rd. mag it comes out to 7lbs. 4oz.. I'm waiting on my Micro H-1, and when it gets here the rifle should weigh a total of 6lbs. 7oz. with a loaded 20rd. mag. This is the first LW build. Although, I kinda through weight out the windows to a point in sacrifice of speed, and accuracy. The next build will be a complete LW rig with only weight in mind. It's raining right now so pics will have to wait. But I'll post one, or two when I can. |

I've got a 14.5" mid length BHF government profile with a pinned 51t, URX3, kac micro rear, bcm mod 1, m300b MOE stock, Emdom sling with an ASAP plate and RSA. Nothing much else, I use low pro rail covers, and don't use either a VFG or a hand stop. I've mostly bought parts that are lightweight as it is. I'm also looking at either a CQBL-1 or an ITAL, rather than the heavier DBALs. Biggest reason I'm asking you guys is it seems like I'm looking at diminishing returns on a lot of the lightweight parts I'm seeing, seems like they're a lot of money for losing 2-3oz. |

Recently I opted to add a Sig Tactical "arm brace" to a 9mm "pistol" I put together last year. The first thing I noticed is the Sig Tactical arm brace is heavy. It registered at 11.75 ounces on my scale. I have no intention to ever use it as an arm brace. That in itself is some Quasimodo bullshit. Shouldering it works about 80% as well as say a CTR stock.
It worked so well that I'm considering building my Magnesium receiver set as a pistol in order to go with a shortened barrel set for weight/size reduction purposes. I may have added a few ounces by selecting this brace, but the weight is in the rear of the weapon which actually helps center it.

Nothing much else, I use low pro rail covers, and don't use either a VFG or a hand stop. I've mostly bought parts that are lightweight as it is. I'm also looking at either a CQBL-1 or an ITAL, rather than the heavier DBALs. Biggest reason I'm asking you guys is it seems like I'm looking at diminishing returns on a lot of the lightweight parts I'm seeing, seems like they're a lot of money for losing 2-3oz.

General goal I'm after is keeping the rifle sub-10lbs. Gotcha. 8.7lbs= 8lbs 11.2oz. Is that your weight or is it 8lbs 7oz? I'll assume you mean 8lbs 7oz. So with your current set up switching the vortex for the m4s you'll gain 19 oz putting you at 9lb 10oz. A dbal d2 is 12.5oz, that would put you at 10lbs 6.5oz. So you need to cut 6.5oz off your current build to make your 10lbs goal. More info on current set up, i.e. Barel length/profile, rail system, muzzle break, grip, butt stock, buis...and anything else I missed. Shaving 6.5 oz might be as easy as switching out you butt stock... Correct, 8lbs 7oz, I suppose I should have been more clear.

You can lose ~3oz by switching to a battlelink stock and magpul k grip($70 for both). If the cqbl-1 or the ITAL are ~3.5 oz lighter than a dbal d2, you're good! |

Recently I opted to add a Sig Tactical "arm brace" to a 9mm "pistol" I put together last year. The first thing I noticed is the Sig Tactical arm brace is heavy. It registered at 11.75 ounces on my scale. I have no intention to ever use it as an arm brace. That in itself is some Quasimodo bullshit. Shouldering it works about 80% as well as say a CTR stock. It worked so well that I'm considering building my Magnesium receiver set as a pistol in order to go with a shortened barrel set for weight/size reduction purposes. I may have added a few ounces by selecting this brace, but the weight is in the rear of the weapon which actually helps center it. <a href="http://s1295.photobucket.com/user/jealifer/media/SMG/DSC00534_zps6e962733.jpg.html" target="_blank">http://i1295.photobucket.com/albums/b639/jealifer/SMG/DSC00534_zps6e962733.jpg</a> Nice setup. I hope someone develops a special light weight arm brace for exactly this reason. |

Anyone have a suggestion for an ultralight charging handle?
I am thinking just a standard milspec one, but don't know if there is a better choice for light weight out there. |

According to the figures in the OP, the difference is so small (.3 to .4 of an ounce) that I am going with the Raptor anyway, for performance. An ounce or two on every part makes a big difference, but it's hard to save weight on a part that is so light to begin with. From OP: Charging Handles PSA Milspec 1.13 U Spikes Milspec 1.07 U Rainier Raptor 1.42 U BCM Gunfighter Med 1.24 U BCM Gunfighter Small |

I really like the BCM gunfighter charging handles, although they are about 0.1 oz heavier. They are stronger and sturdier on a part I feel is kind of a weak link. But the milspec charging handles are the lightest I've found.

Or get the other TI one posted in here for 1/2 the price but it is 5.6oz vs boomfad 4.6 and both are still lighter than a JP lmos @ 6.25oz (these weights are without bolt but a stacked gas key) |

Looks like CMMG no longer makes the Micro gas block for 0.625" gas seats. Which pretty much leaves V7 or the SLR Sentury 6. Both are somewhat pricey options.

Not sure if they use the same piece for .625 and .750 but worth a call. http://bte-usa.com/parts/set-screw-micro-gasblocks.htm |
