I also oddly enough keep hearing phenomenal reviews about PSA's sabre trigger. Given that it's only $80 i'm tempted to try one.

Looks sensational. How does it shoot and how is the weight?
very nice build!
Everything in that photo is 17.0lbs, empty magazine. I do have a set of weights that add another 12oz, making it a lot more stable from a bag.Looks sensational. How does it shoot and how is the weight?

possible optic will be as it will stay under 6# and maybe just under 5# 12ozs

It's a 5x optic which will get me to almost 900 yards with the right bullet according to ballistics. I'll probably won't shoot that far, but never know? I just wanted the 10" for velocity.Dang! That’s light, especially with that barrel. Not a knock, use what works for your needs, but why a red dot with a 20” barrel? Or I guess another way to put it “Why so much barrel for something with just a red dot?”
Again, if that works for you, cool. Genuinely curious.

And BTW, your gun looks like my light(ish) weight AR10 (pencil profile 16” barrel, and a lot of V7, Smoke Composites, etc.), and my uber-light no tax stamp AR15 build (also with a 16” barrel) had a baby that grew up to be bigger than dad!

That’s pretty cool actually! I knew they made a 3x, but wasn’t tracking on the 5x sight.It's a 5x optic which will get me to almost 900 yards with the right bullet according to ballistics. I'll probably won't shoot that far, but never know? I just wanted the 10" for velocity.
if you're referring to post 1,040 it's an ultradyne and the rear only has windage adjustment, but the front has wind and elevation adjustments.That’s pretty cool actually! I knew they made a 3x, but wasn’t tracking on the 5x sight.
I’ve actually been very impressed with the crispness of their dots, durability, and ability to hold zero with their advanced (higher end) red dots. I have them on a couple of the ranch rifles, and often recommend them to friends/family who want a red dot but don’t want to spend Eotech or Aimpoint money.
I only have one of their OG 1x micro prism sights with the ACSS “Cyclops” reticle on a PCC, and it works well for my needs. It’s used primarily as a longer-range tool that takes the same mags as the G21 I usually carry on the ranch, but don’t have enough rounds through that platform yet to say it’s a keeper.
Would love to get a report down the road on long-term reliability of yours; especially on a heavier caliber rifle.
Also @Top O' Texas what BUIS are you running? Kind of look like Bobro, but can’t quite make ‘em out in your pic.
You need less gas to bring the ejection pattern around to 3-4. not more. 1-2 is over gas or undermass.gave a test run on my AR6.5PRC build and it went well, but could've been better. shot 2 rounds, ejected @ 1-2 oclock, shot 2 more after 5 more clicks out, shot 2 more with fully out and still ejected at the same as 1st 4. opened up the upper and checked the buffer.........i had a 9.5oz rifle buffer that caused this. i'll either install a standard weight rifle buffer and/or take another lower and use carbine between 3.5-4.5oz. brass looked good and ammo used was factory norma 143 golden target match which was great, cause the mag (larue) accepted the length @ 2.860". norma must've made them for short action lengths. no other factory 6.5PRC ammo to compare with as some could be for xm length mags?
Closing/choking it off (ie, reducing flow/pressure) it will short stroke.You need less gas to bring the ejection pattern around to 3-4. not more. 1-2 is over gas or undermass.
I apologize, missed the PRC part whoops.Closing/choking it off (ie, reducing flow/pressure) it will short stroke.
Build specsI apologize, missed the PRC part whoops.
Have you posted build specifics for this in another thread?
What I said is generally correct, but 6.5 PRC is a bigger case. Tuning per ejection pattern with the PRC could be misleading.
The only scenarios I’ve seen that fit your description:
1. Gas port on the small side = unresponsive gas adjustment.
2. Gas tube short not enough engagement in gas key.
3. Short dwell timing i.e. long gas system combined with shortish barrel. For #3 I’d agree, reducing buffer/carrier mass is what I would try.
I would check gas tube engagement for sure. Should land about middle of the cam pin cut out in upper.Build specs

Not all +2" gas tubes are the same.
Both barrels below are RL + 2" & yet tubes are not the same.

when shooting i used factory hornady 123sst and amax ammo. shot once then shot a second time, thought i missed so went and checked and found that the 2nd shot was almost exactly in the 1st (just slightly oval). that cbi barrel is a keeper for sure!i have that same barrel and it shoots great. what recoil parts (and weights) are you using?
I am using a KAK Industry BCG and the standard PSA buffer but I have an adjustable gas block up front that I tuned to give just enough gas to hold open on an empty mag. Muzzle Brake is an AR-Stoner. I was using Hornady 130gr ELD Match the picture is with RL15 and I have a batch with Varget I need to test as well.when shooting i used factory hornady 123sst and amax ammo. shot once then shot a second time, thought i missed so went and checked and found that the 2nd shot was almost exactly in the 1st (just slightly oval). that cbi barrel is a keeper for sure!
Also, one thing I wound up doing was putting some shims between the barrel and the upper receiver to get the feed ramps a little closer. Used an Aero Precision Barrel Shim Kit LR-308; they managed to go behind the index pin without me having to cut them like I have seen in some videos.i have that same barrel and it shoots great. what recoil parts (and weights) are you using?
so far only factory ammo in all of my ar 6.5creeds. in the ar 260rem i shoot the 130edl-m match ammo as there wasn't any 123's at the time.I am using a KAK Industry BCG and the standard PSA buffer but I have an adjustable gas block up front that I tuned to give just enough gas to hold open on an empty mag.

Usually that’s normal.Quick, potentially dumb, question: is it normal to not be able to put the safety on after releasing the trigger on my ar? I.E the safety can be switched off while cocked but only put on with it cocked
That’s good to hear, thanksUsually that’s normal.
If the weapon is not cocked, the lever can’t be pointed toward SAFE.
How tight is the barrel extension inside the upper on those Seekins? Ie they have to be thermo-fitted?View attachment 8368955View attachment 8368956View attachment 8368957View attachment 8368958View attachment 8368959View attachment 8368960View attachment 8368961View attachment 8368962Just finished hammering together another really nice 6.5CM: Seekins SP10 Builder's Kit, done up in Accuracy Int'l Dark Earth Cerakote; Rock Creek 5R SS barrel by Craddock Precision; SLR adjustable gas block; JP FMOS bolt carrier group; JP H2 Silent Captured Spring Kit. I thought I'd see if it wanted to be a shooter, so I threw a scope on it. With no gas system tuning at all, groups were immediately sub-MOA with the first box of factory ammo I picked up.
While some may decry PSA, their large frame receivers are very serviceable as long as you keep an extra bolt catch or two on hand. This is coming from a guy who has used a bunch of receiver sets from old school DPMS to LMT to SR-25. Very functional basic build.PSA receivers

No. Have you measured case shoulder growth on fired brass from both bolts to compare? What kind of ammo are you shooting? Factory or reloads? Do you have a headspace comparator?It’s a long story, but I ended up with 2 bolts for my Ar-10: the nice, smooth nitride one from my RCA BCG, and a phosphate Fulton Armory one that got sent free with my barrel. The Fulton Armory bolt is headspaced for the barrel; the RCA is not, but the bolt closes over a round and there are no problem signs on fired cases (to my very limited knowledge). Could I expect better accuracy from the headspaced bolt? Is it worth switching out and shooting a ton of groups to see?
I just got a Seekins builders kit and slipped a Proof barrel into it. It was not snug. I'm rebarrelling to a custom chambered Mullerworks and using an Etune 6.5 extension so it doesn't really matter but guess I got an upper built on a Friday afternoon. I'm interested to see if the Etune extension is snug. If it's not, my Smith is just going to loctite it.Barrel extension outside diameter is the other potential variable in the upper-to-barrel fit equation.
I only build SP10's with Craddock or Proof barrels. Both are a snug fit in the Seekins upper, and thermal fitting is usually required.
I have a good deal of exposure to the 22" SS barrel with suppressor in the Seekins SP10 kit. One of my top shooting buddies had me build one just like this for him. He's using a HUXWRX Flow 762 Ti. He gets sub-MOA 10-shot groups with Federal GMM and their 140 Match Kings.
He's got about 300 rounds through it and has never cleaned it. No telling how well it might shoot if he bothered to punch it out.

Yeah I haven’t tried one yet. I plan on taking my long distance build out to my buddy’s land and start stretching its legs, and I would much rather stand than crawl around in West Texas’ dirt, rocks, and rattle snakes lol.As Powdahound said above, you won’t be standing completely upright.
Even at 6’10” I’d suspect the 71.1.” plus rifle/scope on top will be satisfactory. I’ve been seeing a few of these RRS tripods pop up used lately.
