The Mega barrels don't have any type of chrome lining or anything do they? This isn't really needed for a .308 SS barrel?

It does have the nitride finish inside and out which is a type of Salt Bath Heat treatment (similar to glock) that hardens the material. In many studies it's outperforming chrome. I figured it was worth a try since the cost isn't too far off other stainless barrels |

A UBR. I think the UBR would balance you gun out and make it dead sexay!!! Just an opinion, mind you. |

Thanks. Currently it has a MOE rifle stock on it. I had a UBR on a 20" rifle once but didn't care for the added weight and narrow cheek piece. They are tough though. Just not my favorite. So far it's been ACS>SOPMOD>PRS>CTR>A2. I'm thinking the Moe rifle stock will be just about perfect.

mine gave me 2 weights, 10.8 lbs and 11 lbs with optics and empty mag. When I add my 6-9" bipod and offset sights it weighed 11.8-12 lbs. Prior to the optics it weighed 9-9.2 lbs.
I don't know how accurate the scale is, I tried getting a another weight on a baby scale but couldn't get it to work. |

I'm guessing mine is gonna be in the 11.5 to 12.5 range, even with an "A2 style" JP 22 inch barrel and the recon mount and a standard AR-10 buffer.

I got an eatsmart kitchen scale to aid in processing the deer I get with my MATEN build. So I figured I'd use it to weight the rifle itself:
It weighed in lbs or grams only (not oz) so I converted the lb decimals to oz. http://i1011.photobucket.com/albums/af237/phizzle99gst/IMG_0794_zps21f7a6b7.jpg http://i1011.photobucket.com/albums/af237/phizzle99gst/ASDF3_zps6495cf30.jpg |

Well, after spending two weeks reviewing this thread, I have dug my MEGA MA-TEN matched upper/lower out of storage, dusted it off and pledge to finish the build I started 10/20/2010. Yes you all read that right.
 Due to wife becoming EX-wife and other issues (Obama), this has been on a VERY slow burn, to say the least...
So here is what I have so far acquired over the 3 1/2 years: Upper/Lower (obviously) Geissele DMR trigger BAD-ASS CAA-SRS stock w/mono-pod CAA grip What is planned: MI DPMS 308 SS FF handguard 18" barrell done by Harrison at AR15Performance (hopefully, if I can talk him into doing more .308s) specs to follow once I know them... BCG done by Harrison as well Adjustable gas block, not sure which yet, consulting w/Harrison Surefire muzzle brake threaded for suppressor Norgon ambi-catch Armalite AR-10 buffer A2 buffer tube Tubb CS Flatwire spring So I have a couple of questions for the community: I have been looking at the small parts, is there any difference in quality/reliability between the parts from Del-Ton, Palmetto State Armory, PF Firearms, Armalite etc.? I am also considering just picking up parts at the Chantily Gun Show in a few weeks. Built a 6.8 in 2008 as my first build (lower) and got bit by the bug. Been talking with Harrison ever since so that is why I plan on having him do my custom barrel, and I will get a new barrel for my 6.8 as well. I got hooked on the CAA adjustable stock/grip on my 6.8 and love them so keeping that consistent across rifles. |

CMR 14" Wilson Combat TRIM 14" MI Keymod 15" Other... Going with w SLR adjustable gas block, and the clamp on will fit under the TRIM rail, and I would prefer a clamp on over a set screw. |

My MEGA 308 upper does not have feed ramps. I looked into one of the AR15s I have that does, and here is the difference that I can see. It appears that the entire feed ramp is machined into the barrel extension on the 308 barrel (I have a Rainier Arms Ultra Match) and it matches up perfectly with the MEGA upper without feed ramp extensions. I'm guessing the 308 cartridge must ride high enough in the magazine that the bullet tip does not come in contact with the upper receiver. And to be clear, it does not look like the case where a barrel has the ramps and the receiver does not, leaving a ridge/lip (the inverse of that is known to cause feeding issues). It looks like this is the way the platform was designed to come together and there are no obvious hard edges or lines or anything that looks out of place. Hopefully that helps. |

Noticing the same thing you did, barrel (Kreiger in this case) had ramps and upper did not, I called Mega and asked them. They said that because their parts are used with a wide variety of parts and all custom built the let the end user decide to cut ramps or not. I cut my ramps in with a dremel and just took my time. Looks great and everything feeeds a little smoother. Just do it. |

I know it will work in this arrangement, but if this is not normal then I will give Mega a call instead of sending the upper to ADCO. Okay, I just went and opened the safe so I could see for myself. My MEGA 308 upper does not have feed ramps. I looked into one of the AR15s I have that does, and here is the difference that I can see. It appears that the entire feed ramp is machined into the barrel extension on the 308 barrel (I have a Rainier Arms Ultra Match) and it matches up perfectly with the MEGA upper without feed ramp extensions. I'm guessing the 308 cartridge must ride high enough in the magazine that the bullet tip does not come in contact with the upper receiver. And to be clear, it does not look like the case where a barrel has the ramps and the receiver does not, leaving a ridge/lip (the inverse of that is known to cause feeding issues). It looks like this is the way the platform was designed to come together and there are no obvious hard edges or lines or anything that looks out of place. Hopefully that helps. Can you send some pictures? |

I don't have them either in the receive, but the extension has them. I'm not worried about it. |
