I run as light a system as possible. I have a modified standard carbine buffer (1.9 oz) and have removed material from the bolt carrier to reduce weight. http://wcr.us/guns/ar1015.JPG
I assume it's full-auto because you've mentioned your concern with cyclic rate previously
. I'm really interested in knowing, where on a F/A carrier can you remove material?
Your black rifle shows marvelous craftsmanship, she is a true work of art. Sadly I can't see the pictures now (the links worked before), even when I paste the whole link I just get a generic no dns entry error.
I will attempt to fix dns issue (it should be resolved now but may take time to update to your DNS server).
I have a select fire AR, it is not the one in question (I have an RDIAS so I could easy run this upper FA by changing the bolt carrier).
I have two cyclic rate issues with which I am constantly tinkering; one to make it light and fast (the AR that is the topic of my previous post) and one I am trying to slow:
My select fire I am constantly trying to slow down; to reduce the $$$ that spews from my barrel and make it more controllable and, because it is also suppressed the gas blow back is considerable. I am also trying to delay unlocking the bolt as long as possible for three reasons: to improve accuracy, to reduce the noise level, to keep that nasty gas out of my face off my gun.
Things on the suppressed select fire AR that I have tried and work:
I made an adjustable gas block, there is a picture on this site of it.
I run an LMT enhanced FA bolt carrier. They are designed to delay unlock. As a consequence they vent more gas out of the receiver rather than inside the receiver.
I run an MGI Rate reducing buffer. I tried hydraulic buffers but the MGI seems to work better.
I run a Dave Tubbs buffer spring.
All those steps have helped; if anyone has other ideas please let me know (short of going to a piston system of which I am reticent).
I chucked my bolt carrier in an endmill and cut nearly 1/16th material from the inside as far up as my tool would reach (about 1 1/8th) then I cut material from the outside starting 1/4" from my inside cut and ending just before the bearing ridges at the front of the carrier. I'll take some pictures of it some time.. I am lazy you know.
Edit to add:
My apolgies for the hyjack!
Also, for those who are interested, I am hooked on carbon fiber forestocks, they are so light its like they aren't even there; and although not as tough as an aluminum rail they are tough enough.
I have a couple monolithic type uppers, an LMT MRP and a Vltor VIS 2. I continue to use the monolithics on my select fire guns for one reason only:
When assembling my uppers I use a 99% silver solution (made for heatsyncs for computers) for the interface between the barrel extension and the upper receiver. This makes an effective heat sync (there is a lot of aluminum in that receiver and rail) great for full auto fire. On my semi ARs I wouldn't switch back to rails for all the tea in China. You can get bolt on rail strips for the carbon fiber forestocks so if you wish to mount something like a vertical foregrip, light, non visible laser, etc, you can. I don't like heavy so I don't hang much on my rifles.
