Plugging your midlength gas port and drilling another at rifle or intermediate length will not be realistic. Your gas journal diameter is 0.750, but it probable tapers or steps down to 0.740" after that journal area. Finding a gas block for a 0.740" barrel won't be possible. All this intermediate length gas is a new thing, mainly coming from Wilson Combat. It works, if done properly. It's not at all common, though. White Oak Armament will make you a proper gas tube, in any length that you tell them.

^^^ Truth right there. Heed those words. Yes. Krieger/Criterion used to make a barrel specifically for Fulton Armory, 16" rifle gas. 0.936" gas block journal size with a 0.105" gas port diameter. Flawless barrel, runs like a champ. @DNPhas one of those barrels. Criterion now makes a 16" rifle gas barrel with a 0.750" journal diameter, and I'm working with a guy right now to figure it out. His gas port seems right, but time will tell. That gas port diameter works with 18" midlength gas barrels, but you're gonna need something at 0.090" or slightly larger for a 16" midlength gun. Because of the shorter dwell time. You won't need 0.095", but you'll need 0.090", maybe a touch more. Positive on that. <<< That's with a proper recoil system, spring that's designed for a .308 and not AR15, and a buffer that weighs 5.4 oz or damn close.

Yep, that's a legit old DPMS LR-308, with their target slickside upper. Serial number end in a "K"? That'll tell you if it's a factory built LR-308, or if someone built it from stripped receivers. All the stripped LR-308 receivers they sold had a "K" stamped at the very end of the serial number.

All DPMS LR-308s are the original design, and not a DPMS G II. All the G IIs are not marked LR-308. Is this a lower you built/machined, like somebody's 80%, and you're calling it a LR-308, or is it a real DPMS we're talking about here. Has this gun ever fired before? You've shot it? Or is this all a brand new build? Need ALOT of information on all the parts used, if you built it. If you purchased is from someone, it could be a FrankenGun, put together with all kinds of shiit. DPMS never made an upper for the LR-308 that didn't have a forward assist, unless it didn't have a shell deflector also. THey made a slick-side that doesn't have either, but if it's got a shell deflector, and no forward assist - it's not a DPMS upper receiver. The DPMS LR-308 upper receivers are pretty distinctive - nothing else on the market or made ever looked like them. They were made from an extrusion. Here's the slickside "target" upper, with that huge rail: Here's what the rest of the DPMS LR-308 uppers look like - the forward assist was always incorporated into the shell deflector: Hope that helps...

NICE!!! Glad you like it, man! It's a damn good light.

Once again... Let's get this moved to somewhere appropriate. This ain't the section for this...

I think we talked about this in another place, but here's a good article on it, and it fits in this section. There's an embedded vid in this news article. Worth watching. https://gatdaily.com/a-new-form-4473-again/?utm_source=GATdaily&utm_medium=email&utm_campaign=12_14

Did they have the blem 762 tools? I'm grabbing a couple more M4s, just because. nevermind, I finally found the page where that was at. No blem 762s, but the deal on the M4s is sweet! https://catoutdoors.com/product-category/tools/

When we were out at the SDTF, we heard the miniguns from Dillon's Range - which isn't that far away from us. We heard those things going, and it was cool as shiit. Here's what was going on over there, just a couple miles away at the Dillon Range... https://www.recoilweb.com/technical-k-o-minigun-equipped-ford-ranger-177162.html?utm_campaign=249632_Recoil newsletter 12%2F2%2F22&utm_medium=email&utm_source=DotDigital&dm_i=7C6R,5CM8,2I8GXU,QDLY,1

Is it what you thought it would be? - you've read the AARs from years past... Did it live up to what you expected?

I love it when he goes off, and the spit starts flyin'...

That's exactly why I love you assheads. That very reason. Thank you, for being you. You let me, be me. My hat is off to all of you, for sticking it out, and hanging around...

I love the Cat M4 tool - it really works. I don't have the bigger version yet, but I'll pick one up now, based on what you're saying. I do have the OTIS Bone Tool in both small frame and large frame. They work well for cleaning the BCG, just as well as the CAT, but that's all they do. The CAT does a few other things that the Bone Tool (single function) does not. Right on, man. Thanks for writing that up... Post the link where you found the blems, and I'll grab several.

VERY NICE, RENE!!! You know - you're welcome here anytime. If you're missing that, just head out here... I'm just sayin'...

LaRue MBT I see a trend here. LaRue MBT-2S. I have about a dozen of them, maybe more. I know I've bought about 2 dozen of them, just to get the bulk-buy, just to buy some for friends, and get them to them cheaper. I used to be a Geissele snob, nothing but - and I'll still use a Geissele Hi-Speed National Match trigger - but it better be a very special build for me to shell out $300, over the $80-ish that the LaRue will cost me. The LaRue is that good... I have a few competition guns that I shoot, and they're all LaRue triggers. I have 3 precision guns, built way back in the day, that have the G Hi-Speed National Match. I'll never turn away from those triggers - they're the very best. Spend what you want to - outshoot the trigger, and come down to that point where the trigger is what's holding you back. At that very point right there, when you realize that - my trigger is what's costing me the accuracy, I've out-shot everything else on the gun - it's time to dump that LaRue trigger, and buy a Geissele Hi=Speed National Match trigger. Think about that. Think about you, and your shooting. Determine what's really holding you back. Determine why you're now outshooting your gun...

@rpoL98 - good to see you hanging in here after the years. Don't go away - stay around man.

Shocks me as well. First M5 extension I received from them many, many years ago, internal depth was 7.100" internal. Shiit. That's no even a spec to look at, at all. It was shocking. Disappointing. They're still shipping those... I wish they understood carbine recoil systems for large frames. They just don't. Seen some of the CS Reps tell people, "You need to run the rifle recoil system for that gun..., it's the 18" barrel..." <<< The most foolhardy thing I've seen posted, ever... Yeah, the one with the proper recoil spring, and a 5.4oz standard rifle buffer. Same as running the proper recoil spring (Same spring if you're Armalite, the EA-1905 spring - works rifle or carbine recoil, AR-10. One spring really does do it all), and the H3 (5.4oz) carbine buffer... Common sense isn't so common, anymore... They send you the H1 buffer, at 3.8oz... The logic just doesn't compute, for me. I understand the basics - I don't understand how they can tell you the 5.4oz rifle buffer system will work, but you purchased the 3.8oz carbine buffer system from them, on a complete gun... Go back to the drawing board, guys. Do the BASIC math. It's right there in front of you, for fuk's sake... Buffer mass makes ALL the difference in these things.

We'll set that Mile up for an additional target at 2,000 yards. That development is starting now, and we'll have it finalized before Spring Shoot. Never stop.

Yes, it certainly would be. Not to mention the condition of the bolt lugs, and the condition of the barrel extension, from all the "over-gassed" violent locking/unlocking... ...because the recoil system is too light and not up to the task...

THAT'S the spirit!

Indeed.

That Mile-Shot changes your perspective about shooting... Makes 1,000 yards seem ALOT different.

Here's a complete list of roll pins in ARs. This is for AR15s, but it's the same stuff for the .308ARs. https://www.biggerhammer.net/ar15/pins.html

I want to point this out, currently. I will be pointing this out, in the near future. Just because I've BEEN a violent man, does not MAKE me a violent man. My situation dictates what I need to become. That's not some fancy Sun Tzu shiit. Those are my words. To get into this further, you need to read everything ever written from Lt Col Dave Grossman. He has 14 books. All are worthy.
