So I finally got all my parts together to build a pair of Devgru clones and I'm getting ready to do my form 1's. What is the overall length with a SL-K stock? I have my receivers all boxed up ready to get sent out for Cerakoting so I don't want to unbox to figure out to oal. Thanks.

Does anyone happen to have a Gen 1 lower they'd be willing to part with? I ordered one from Capital Supply and after being lost by the USPS for almost a month it gets here and it's a....Gen 3. Of course they have no more Gen 1s.

AAC posted on IG they're still getting/qc'ing parts for the m42000s.
"trying to source components that aren't as easy to get as stainless steel plus having the raw materials takes time. With most of the nickel ore that goes into true 718 lnconel coming out of Eastern Europe makes things even more difficult. We apologize but we're not gonna put out a product with sub-par components just to meet a proposed date" |

 Attached FileThrew it together based off a poor quality video . It showed what looks like either a 1-4 or 2.5-10x24 in bridged NF rings along with a Wilcox OASYS mount in front of it. No can, AFG, and what appears to be a m340v but definitely a scout style light. Probably an ngal on the right side of rifle but no way to tell 100%. Also appeared to be a dead air flash hider but I couldn't tell the caliber. |

If you’re 100% sure it’s a scout and not the olight, that’d be kinda unique as I believe it’d be the first sighting of a modern SF light on a dev gun since the old 600Bs.

Gen 1 lowers are absolutely cooked right now, people trying to sell them for $400+ stripped. Why did DEVGRU decide to go with a generic milspec lower? I have half a mind to get an unmarked lower and see if someone will just engrave it with the correct markings then cerakote.

The stainless barrels will wear out with quick tempo semi auto and full auto firing with the rifling literally no longer existing in the barrel at a certain point. I couldn't tell you the exact firing schedule or number of rounds, but it does happen. Seems like they prioritized precision over durability. Your clones probably won't see tons of rounds put them in a short amount of time or 10,000 rounds so it's a non issue for you guys anyway. |

You can say the same for any barrel as none are impervious to wear. While we have no idea how Noveske determined the number they gave to DEVGRU for expected parts life or what the "mission critical" data point is, it still implies that the durability of these barrels are being significantly underestimated by a few here. To the point where barrel life won't realistically be a concern more than any other similar setup. Originally Posted By medieval_flail: Is there a MK18 or URGI user manual that shows barrel life?

Haha I was literally about to respond with that - people used to lose their shit over DD's earlier Mk18 uppers with the larger ports like it was most horrible thing in the world. Then again, I'm not a high volume shooter doing suppressed mag dumps with thousands and thousands of rounds every month. My larger port DD Mk18 upper has been just fine (I don't even recall a single issue with it either) in the almost 10 years I've had it. |
