I actually just bought a carbine length straight gas tube. I think I got it from them. So it’s a true DPMS/AR15 gas system straight tube. Works out great so far. It’s easy to switch where it’s at but I will never switch it after I find the seeet spot. Which is closed as much as possible lol. I will 99% never run this unsuppressed cause the 10.5 with a brake just hurts to shoot 😕

So…just now installed today. It was very tight. Almost too tight. I don’t ever want to disassemble this thing. The rail gives me just enough clearance to adjust the rifle speed gas block. Sad thing is,it’s set in the most closed setting out of 12 positions and it cycles decent. Ejection is 2-3o’clock. Apparently you need to buy different plungers to have a different range of settings. id like 3-4 o’clock ejection so i need to get a kit from them to close off the port more. The KAK 10.5 carbine gas port was .071”. My cut down BA 12.5” barrel was I think slightly smaller which was enough to cycle on any setting. I still have the BA I cut to 10.5” from 12.5” atleast but I wanted to try this KAK barrel. I like the rails look very much. This size is very handy but I gotta ask an opinion from everyone. Is this 10.5” 308 worthy of a 1-6 like it has or should I save it for another setup? Should I go red dot and x3 magnifier instead? Still bulky either way or just do a red dot? This build was supposed to be an upscaled mk18. Just curious in what everyone thinks. this is a fun gun. It might see occasional 300+ yard shots on steel. I might go to TX to visit a good friend and hog hunt. Hope you guys like how the rail turned out.

Shes a beaut Clark. It’s close enough for me so I’m happy. I need to replace my barrel at this time so when $$$ comes in I’d like to show off the SBR quad setup. it’s simple enough and straight forward to install. Just pricey.

https://centurionarms.com/centurion-arms-quad-for-7-62/centurion-arms-8-7in-free-float-quad-rail-7-62/ Just bought this one in hopes it completes me. Going on my 10.5” 308 SBR. Hope to have a picture up next week and a small review. Fingers crossed it will bridge the gap between my heart and a DD Lite rail. this is a birthday purchase. A $400 part for me nowadays doesn’t happen much ever anymore.

Will do. Thanks for the info.

way more info on the form1 forum but I talk about it vaguely due to YouTube’s butthole stupid politics. I think my YouTube days are closing in anyways.

LCP baby!

I like this topic. I actually wanted to do a video about my edc and why. It’s sorta gonna be rude but I don’t care lol! I have some points to make. Stay tuned gents. I’ll try and make this today.

https://youtu.be/DgrNErtJQWY?si=b1CKxMfBSJ9Kmz1X Just a video with a few of my suppressed weapons for bugging out. Not necessarily what I’d pic though but had to show that the good ol’ fat 45acp can be still be great.

I can’t remember off the top of my head but it was a Ballistic Advantage barrel and I think its port size is listed on a few sites. I’m guessing .62-.67. It looked tiny.

https://youtu.be/JhMTGffFsdA?si=SgZEZhj8laqDJq9a there will be another 2 videos about the entire world of shotgun cans. I have lots of poop to talk about in my journey. More about this build in the upcoming video.

sorry for the late update on my testing this was done a few short weeks ago thought I’d share the results with the 308 community. I’m only apart of 2 forums past few years This one and I’m mainly on the Form1 forum. No reddit or other things. Facebook occasionally but people suck Took my buddy’s chronograph out today to finally test out the 16” 300 blackout 147gr VS the 10.5” 308 147gr. Both are super sonic factory boxed ammo. (Both Federal)These can always be tailored and made better but I wanted to compare factory loads to each other. The comparison is supposed to show how powerful the 308 is in a short barrel going against the longest barrel 300 blackout. There’s always flak against short barreled calibers like this and I thought why not do a test for sure. I’m not a 300blkout guy. It’s a tactical coyote rig to me that’s why I did a 16”. I don’t care for AR pistols/braces and I can get the most noise reduction from a longer barrel and suppressor. So it works out good for my needs. 10.5 308 got a 4 shot average of 2287 fps. 1707 ft/lbs of energy16” 300 got a 4 shot average of 1815 fps. 1075 ft/lbs of energyDifference is 472fps and 632ft/lbs more for the shorty 308. Still about 30% more go-go juice. I’m going to come up with a 132gr cutting edge solid load for this guy to make use of the short barrel. Hope to get 2500fps+ with the right powder.

Thanks guys. im going to do a fun test this weekend hopefully and post a video. for the sbr 308 haters out there(300blkout people…). Im going to use factory 147gr nato ammo over the chronograph. We will compare it to my 16” 300blkout with the same 147gr supersonic ammo but for 300 obviously. I want to see the velocity difference and see how much faster the 308 still is. I’m guessing 2300 from 10.5” barrel. Guessing the blkout won’t make it 2000fps like some of the ammo claims. Maybe it does..we will see soon.

Tirant to me is underrated. Solid performer. When I get a moment I’m going to compare them on the same host. I don’t think the HK platform and 1.25” shorter barrel made the obsidian that much worse. I also felt more backpressure and debris on the face more too with the obsidian

first off. Not entirely impressed. Somehow others are getting better results but I’m not paid. I do this as a hobby and I love building my own stuff. I 100% think manufactures fluff numbers. No questions there. I say it in the description but I would like to test the Obsidian on my 1911 to get a fair comparison. I'm still doubting it will drop some magic amount of DB to beat the Tirant 45. Gonna hope to retest this weekend with more data to share. the can did good just not as great as it’s claimed to be. I still love my Tirant
