SO here are my previous threads about the lower and upper specs.
lower the upper is Balios lite upper 14.5 faxon pencil extended ti v2 flash hider JP ultra low mass BCG Larue tactical bolt titanium firing pin v7 lightweight charging handle slr .625 adjustable Ti gas block RMR Larue RMR mount. BCM KMR 10" V7 titanium barrel nut and titanium hardware Lower is standard RRA lower and the whole damn V7 titanium ultra light lower parts catalog ALG FCG just tossed her on the scale and she came in at 4.4lbs Off to the range to tune the gas system. 
Update, I just switched over to a smoke composite stock, with endplate and castle nut..wow. Lost about 6.1 oz. I could not believe how much more weight I lost with a Minimalist stock, lightweight buffer tube and titanium castle nut and end plate. the new complete rifle came in at exactly 4.01 lbs. I can dip below 4lbs with a bailos little lower or a lighter red dot mount |

Good job. I was going to do nearly the exact thing but got sidetracked. Thanks for being the guinea pig and posting about it!

2a and v7, I love their parts. The gun looks great. What's the weight on the rmr+mount?

This s pretty phenomenal build. I'm very impressed with the weight you achieved with the rules you had laid out. If you could post your tuning experience and outcome, that would be great. Particularly interested in the gas block adjustments and variations with the ammo you used. Other tuning inputs like buffer weight and buffer spring rate/type that you might have tried would be also helpful. I assume you are going for fast follow-ups and flat shooting gun?

My theory behind the extra spring strength it will help compensate fora a lightened buffer. We shall see. I have all the weights still for the buffer. I will tune it for my bulk reload recipe which is a hornady 55 gr bullet backed by 23.5gr of IMR 4064. Its a pretty light load itself.

I'm doing a ULW build but going a different route, as much carbon fiber and polymer as possible. The only thing I couldn't bring myself to justify buying... yet, was a Ti or Al bolt carrier. |

J: You might want to reconsider your choice of buffer spring. My lightweight build has adjustable gas and a Taccom 1 oz buffer. Taccom recommends a special reduced-strength buffer spring, the opposite of what you installed. The idea is, a standard carbine spring will move the low mass carrier back into battery too quickly, inviting "bolt over cartridge" type malfunctions. - CW http://www.taccom3g.com/enhanced-carbine-spring.html Quote HistoryQuoted:

I never thought about it that way, I was only thinking extra spring power to slow the buffer down going back. This covers the extra power going forward with the light bcg. |

J: If you want to knock off some more weight, check out the combination buffer tube and fixed buttstock made by Smoke Composites. Total weight, not counting buffer, spring, castle nut and end plate, is only about 100 grams or less than 4 oz. - CW

I did want to keep my stock adjustable for this build. There are a few other places I could have saved weight but I didn't want to dip into the polymer uppers or lowers and I didn't want a tube for a forearm. |

damn the more I look at that stock I like it. I might have to order it as well as the tactical link light weight recoil system. I might be in the sub 4lb range soon
EDIT. Probably not sub 4lb, read the weight wrong on the smoke composite stock. But I could drop a couple ounces |

Very good looking and well thought out. I'm looking at a 14.5 lw barrel but had no idea about the titanium parts.
Out of curiosity is this a lightweight record? Also, subscribed for a range report. |

snip...Out of curiosity is this a lightweight record?...snip. With a little bit of effort, I got my latest build (in 6.8 SPC) down to 5 lbs, 13 oz. Reducing below 4 lbs is much more difficult and calls for extreme measures like titanium lower parts kits and carbon fiber furniture. In any event, ultra-light ARs is the latest "build it yourself" craze. This makes sense since the AR-15's whole reason for existence has been a military carbine that is lighter and shorter than its full-size predecessors: the M1, M14 and FAL. - CW http://www.thefirearmblog.com/blog/2014/11/23/weekend-photo-ultra-light-ounces-pounds-ar-15/ |

Hey J - Not to nag, but I was hoping to hear how the tuning and range time went for you and this rifle. I am seriously considering doing something similar, but building something like what you have done ain't cheap! So I was hoping to leverage your experience on the parts you used to avoid any issues that you might have encountered. If you're too busy, that's cool...

Hey no problem at all. I have been busy and have not been to the range yet.
I just got in my JP speed hammer. It was recomnded by JP to run with their aluminum BCG. I also got a couple buffers and buffer springs to test. I will try my best to get out and tune this thing but please stay tuned. I also got a smoke composite stock just to play with. It hasn't arrived yet but I was curious and bit the bullet. |

Range report? My first trip to the range was an interesting one. I started a spectate thread because I was getting spark showers out of the muzzle. So when it happened a few times, I stopped shooting. I did find it very easy to tune the gas system though. Got it cycling just fine. It was pretty soft shooting, loud though. I was at an indoor range. Turned out the Sparks are normal with a titanium flash hider and will subside with more rounds down range |

Why not a mag tactical lower or Balios lite lower?
Very nice build btw. FWIW, I run a sprinco Orange spring with a Rhino Arms LW BCG and 3oz buffer to get cycle speeds a little over 1,000RPM from my bump gun. I've got it in a 16" barrel rifle gas gun, had to open the gas port to cycle wolf. No issues feeding from Pmags so far. |
