May have misspoke, 265 gr. 260s are for the 454.

24 of H110 behind a jacketed bullet is a tight fit. What do you end up with for COL? No whimps 44 loading for sure! XTP mags or corelocks? Ever try the 260gr Interlock? Designed for 444 marlin but a good bullet for the 44.

The 99 dollar barrel was there the other day, saw that. The 65 dollar barrels (now 75) say 10 left, don't see the PSA on those. Edit didn't see PSA on the 65 dollar barrels, it's on the 75 dollar ones. So good barrel?

Still there or there again, but 74.99 now. Don't see where it says PSA, but they told me they were being sold to PA. The BCA barrels I looked at had blue/black extensions, these are raw looking extensions. To get there I use the gunbroker search for " 308 barrel spectre " That good or bad?

Spectre supply on gunbroker https://www.gunbroker.com/item/875072664 I have bought a few items from these guys, all good stuff, asked about these barrels they said DPMS pattern, US manufacture, were being sold to Primary Arms but couldn't tell me who made the barrels due to NDA. Any idea? Rule 65?

Welcome from Seattle. You will get a lot of help here, just provide the information we ask (and do what we say!) and you will end up with a reliable shooter. Al

Yes it's a 1:7, got great groups out of both the 40's and 62's. Didn't break the chrono out, sighting in and screwing around, but chrono'd a few 62's the other day still going over 2200 at 69 yards when the radar lost track. Anyway, back pack gun, not worried about long range performance. One other thing, got a couple of double fires with both the 62's and the 40's, slower then a slam fire I think it was trigger bounce. I'll try a couple things and maybe get to the range this weekend. See if I can get a track out to 100 yards.

Went to the rifle range to sight in the shorty, got it hitting square at 100 yards, shooting 62gr green tips, good group, 100% function. then tried the 40 gr blue tips, good group and function, then tried 2 different brands of 55 gr, mil 556 and civilian 223, neither one worked worth a $hit. Maybe dirty? no, went back to the green tips no problem. The 55's are acting like a failure to extract, but get lock back and no issues chambering one with empty mag. Try some different mags and a lighter recoil spring next time.

Looks like a nice block, out of stock this morning. I'm running a seekins on a couple of builds, need a long allen to adjust from the front and the lock screw if you'r lucky lines up enough to get a ball end allen through one of the openings in the handguard. I have one of the superlatives on another build, no lock screw just need long allen adjusts from the front clicks in place.

Send it to me. Just finished up @aadavis94 bolt with hopelessly stuck ejector, ready for the next project.

After working on another members bolt, tried to use what I believe to be a DPMS firing pin in it, didn't fit. Firing pin out of my Toolcraft did. BUT... DPMS firing pin fit my Toolcraft, so, I've been running a small tip pin in a big hole bolt until now. So I believe a small dia pin came in the Toolcraft NiB BCG, new, out of the box. Never looked that close before.

Looks like magazine damage possibly, try loading and unloading mag.

Also, take it from someone who refuses to buy ammo, some powders have a lot more pressure during the dwell. Example in 308 AR-Comp drops off similar to factory loads, similar port sizes work, RL15 builds all the way to the end, exhibits over gass symptoms. Smaller port /less dwell would work fine

Just checked one of these out at the shoot. Death Grip doesn't do it justice Owner has a multi platform with giant optics and quad rail first and last 4 inches of the handguard so clamped it middle of the guard. Locked in solid. No problem being completely out of balance. On sale around here from time to time for 120. Going to get one next sale

No problem. May want to try an AGB anyway, not mandatory but I run them on large frame builds, slow the BCG down until I loose LRBHO and then open up half a crank or so. Not speaking for everyone but my 3 large frames extract/eject/reload the most reliably with the minimum amount of gas necessary.

OK, @aadavis94 ran out 2 clips in the 12.5 sig using the bolt with the oversized ejector, ran fine 2:00 to 3:00 ejection pattern at around 10ft. Funny thing my spare DPMS firing pin didn't fit. Too big. Is this supposed to be a high pressure bolt? Anyway The one out of my Toolcraft fit. The Toolcraft wasn't sold as high pressure, need to put a mike on it maybe they use the smaller pin for everything. Had it in a 6.5cm before buying a high pressure bcg, no ill effects.

Ok, shot the shorty, ran out a couple mags except for the very first round behaved flawlessly with 62gr suprising velocity, 2400 or so expected lot less on a 7.5 in barrel

Getting my shorty out finally, heading to a "Picnic / Camping Firearms Allowed" invitational over east of the mountains. Hopefully I don't encounter @Cliff R type issues. Taking pistols, rifles and carbines from black powder to AR308. 2 new builds that haven't been tested plus the @aadavis94 bolt with oversized ejector in a Toolcraft BC see if that runs in the 308/ 12.5 Sig barrel setup.

And Al's shop when he can't wait for the nationals to finish and WOA to get back to work! Mine came out perfect at 11-3/16" If I remember right. Had to open the port up a bit, think I ended up with .079 and backed down just a bit w/ AGB. Ditto on Orange spring and 5.6 buffer. Also ran fine with the longer extension/ buffer and a Tubbs spring w/ AGB a little closer to W/O.

I am going to give that a try, I had issues at first that I attributed to deformed brass around the rim area, fit in case gauge but really tight and near impossible to eject said rounds live. I have 50 or so rounds that way I've culled out, when I get a chance I'll punch the pin and cycle a few.

Interesting. They also have hardened M2 which they describe as "Drill Blanks" so ordered a couple sticks of each. Didn't have the Core Pins oversized 5/32 (well 0.0007 over, need a little more then that) Not seeing much difference between Hardened M2 and HSS, HSS seems to have a little more heat resistance. Cool place to shop, good inventory, quick shipping, good pricing. Thanks for the tip!

Never heard of core pin, I'll check it out. I use hss drill rod for small punches, doesn't seem brittle. Bends before breaks.

Collapsed and buggered up. Never seen coil spring collapse like that unless from lots of heat. Buggering is at the bottom end, probably from trying to pry out from the witness hole.
