yes, southpaw shooter. Mag looked like a disassembled mag, didn't find the follower. Been thinking about it, 7.5 buffer works in 4.5 in barrel / ipsc 180 gr loads with KVP Extra power spring, Sprinco Red Spring, and EA1095 spring Rare double tap With the EA1095 7.5 buffer didn't work in 16" carbine even with EA1095 spring. 10 oz buffer works in carbine and pistol with Sprinco red spring or KVP Extra Power Spring. Occasional double taps with the EA1095/ Carbine. Didn't try 10oz/1095 in pistol I think with the 16in barrel the dwell requires a 10oz+buffer regardless of spring. Red spring /10oz buffer winner chicken dinner

pretty sure you can get anything to go off out of battery if you fuk around enough with it...

Mere flesh wound good data on the springs

Bloody range report AR40 Pistol and Carbine First tried red spring/ 10 oz buffer in the carbine. Flawless. Even a couple of the iffy mags functioned well. Recoil was sweet. Then took the EA1095 and 7.5 buffer out of the pistol which had been working well with the factory mags, and put the 10oz/ red spring combo in that. great results. Then put the EA1095 + 7.5 buffer in the carbine, had a couple of jams even with the glock mags, and like an idiot I kept going, until I had a lawman 155gr HP go off out of battery blowing one of the cheapo mag into its basic components and taking a chunk out of my chin. Blood everywhere, had to finish up the 2nd project of the session (springs and red dot on a glock) periodically blotting blood out of my beard and off the bench. To summarize, in 7" tubes, 15.5 oz Stern Defense BCG: RED Sprinco/ 10 OZ buffer excellent functioning combo for pistol, carbine EA1095/ 7.5 oz buffer good in pistol, although same combo in the other pistol we built this year did have some double taps EA1095/ 7.5 oz buffer NO BUENO in carbine. Curious why worked with 4.5" barrel with 180 gr IPSC loads but not 16" barrel with 155 gr +P, all other things equal. Forgot to try the red spring with the 7.5 oz buffer, a little out of sorts after the blow to the chin. Looking back from the 50 yard berm

Mild handloads are fine with the right powders. You probably know most /all of this but I like talking reloading Just need enough pressure to: 1. Inflate/ seal the brass to the chamber 2. Get a clean burn 3. Cycle the action- after achieving 1 and 2 here is where I would start messing with different springs, but usually don't need to unless going uber lite. I have had good luck with Titegroup for medium recoil auto loads, leaves a gray coating on the crown but burns clean at medium recoil loads. There are a lot of other powders that fit the bill as well. My medium 45 load is 4.5-4.7 gr Titegroup 230 gr Xtreme round nose 1.265 COL 4.5 gets a little under 700 fps in the Kimber Ultra Carry 4.7 gets a little over 750 fps in the full sized. manageable recoil and accurate. And economical. Cleanest powder I've used is VV3N37 in autoloaders but need to load mid to upper end. (Costs more and uses more, but clean and snappy) Clean up with dry patches.

Got the red spring, it is longer then the extra power JBO/KVP 308 spring, shorter then the EA1095. Got it in the carbine with the 10 oz buffer, report back tomorrow hopefully.

When reloading smoke and soot are typically indicators of under pressure rounds. Maybe the Winchester is a reduced recoil load? 45's are a finicky breed, full power 230 gr ball ammo 1.265 - 1.275 COL always works, every gun I've tried it in, every time. Every thing else may work fine, may not, depending on the pistol. If it was me, I would try different ammo before messing with the recoil system, even if you get it to function, you still have smokey sooty rounds.

I'll take the brass please. I use it for 25-06.

I built an ar-40 pistol and an ar-40 carbine because I had 2000 rounds of xtreme 180 gr pills on the shelf, and a lot of primers, brass, and powder laying around...

That buffer is badass, probably the 120.00 could be better spent elsewhere though. In 2 different builds this year the EA1095 spring was just a little bit heavy even with 7.5 oz and 10oz buffers ($34.00-$54.00) The heavy duty 308 carbine spring (KVP not Sprinco) is maybe just a little light, excellent function but the buffer bumper takes a bit of a beating and can be felt in the recoil. If the red spring was half way between it would probably be about right. Free shipping, no tax, got one on order right now! Let you know...

at the risk of becoming a troll I'll say I ran through a couple ea 15 and 22 round Factory Glock new gen mags today absolutely 0 issues. First feed to lrbho. waiting for the 22s to go on sale.

* 10 oz Tungsten 4-1/8" buffer

OK, tried the carbine today with: Extra power 308 carbine spring 7 in tube 10 oz KVP 4-1/8" stainless steel buffer Glock gen 4 22 round and 15 round mag 155 gr Ranger HP ammo / 1500 fps Flawless operation off shoulder, fed perfectly, no double/ triple bursts, LRBHO BUT a little more felt recoil then the 7-5/8" tube and the EA1095 spring. Buffer bottoming out for sure. Still peppered the 100 yard target. Seems like a reliable combination, just be replacing buffer bumpers occasionally.

I thought that was the 45 with the chipped receiver.... .40 bad feed... 45 single shot... now I'm confused...

The range loves to point out shortcomings. Gravel pit can be an even more brutal master! As I've posted elsewhere, the 40 does not like cheap magazines. I'm sure you will finger everything out!

SGM mags will also suck in a 40. Who's barrel did you use? Seems like the 40 is a lot more tempramental, magazine wise. New gen glock mags work the best. Also the no-name 31 rounders from Classic Arms work 99% RWB GL40-31MAG. While the BCG is small enough that it won't ram the ears of the receiver if it goes back too far, it will be traveling a lot farther and therefore faster when it strips the round then I think would be ideal, I think you want to limit travel to about 1/8" past bolt catch. I would suggest heavier buffer and spacer or get the longer buffer style. Here is a typical spacer if you don't have tools to turn your own one: These are a couple samples for heavy buffers pistol caliber length from Joe Bobs: (1) KVP 7.5oz Stainless Blowback Buffer (1) KVP 10oz Tungsten Blowback Buffer This is a another option to the Sprinco spring: (1) KVP Extra Power 17-4 SS PCC Spring

I know I'm not 98, but: A good way to tell what the recoil system is doing is look at the buffer bumper occasionally. In my opinion it should show signs of bottoming out but not beating itself up. 20ft at 4:00 sounds about right. Experimenting with different springs and buffers is the name of the game. Running reliability? What is the weight/length of your buffer? I'm running a 10oz in my 16in carbine with a 308 carbine spring.

So the Oly 45, special mags for millspec magwell to feed 45ACP bullets?

Nice looking weapons. The Sig SB15 brace is on sale for $74.99 in FDE, I grabbed one but haven't put it on anything yet https://www.sigsauer.com/store/sb15-pistol-stabilizing-brace-kit.html

Out at the gravel pit Saturday I was exploding potatos at 100 yards offhand even with a little fog in the scope. We also blew the "Mongo Scarecrow" a quart sized tannerite type exploding device I've had laying around for many years.

Gotta quit spending money, but... Leupold started rattling and had a little fog in it! Spent 20 years on the BAR 338 WinMag but only lasted a couple sessions on the 458. So Gold Ring is going back to the maker for a tune up and the SOCOM gets a Viper PST 1-6x24... I'm impressed with the PST, beefy...crystal clear from 1X to 6X, Milrad retical. I 458 uses a 308 sized rebated rim so the 308 boresighter worked perfectly (with a small mod):

OK, so what works: 7.5 to 10 oz buffers 4-1/8" extra power carbine spring in a 7" tube Ea1095 spring in a 7-5/8" tube, but, not with the 10 oz buffer. Need a spacer but not a stack of quarters, don't want to space the spring, just the buffer. See image below. Factory glock mags. There is a 22 rounder that we have tried out works flawlessly, also the 15 rounder. Also the Korea RWB 31 rounders, GL40-31MAG, but not the SGM's, SGM-40G31R We have built 3 so far, two 4-1/2" pistols and one 16" PCC. I believe they can be over buffered/ over springed, if you start getting double and triple bursts that may be the culprit. Had an EA1095 in a 7" tube/ 7.5 oz buffer and it doubled up several times, went to the EP carbine spring, fine since. The PCC was doing that Saturday at the gravel pit but has never done it from the bench, close balance 10oz buffer EA1095 spring 7-5/8" tube and spacer. Changed it out yesterday. IMAO the BCG can travel back far enough to eject and feed without going back far enough to set the disconnect, if you don't believe it, pull the firing pin and try. This is what I did: Pulled the charging handle slowly back until it picks up the round, feed it in, and pull the trigger. No Click! Hammer had followed the BCG back down. Do it fast and BURRRRP! We run a stock MilSpec FCG, and a Stern BCG. A little taller hammer like maybe some of the heavier 308 type might fix that, or a slightly steeper ramp on the BCG, or a lighter hammer spring. Fine balance. My old AR15 has a cut BCG and a notched hammer so it locks up if the disconnect is damaged or disabled to prevent slam firing, but as far as I can tell, these are just waiting to go full fun mode. Sample buffer for photo, not the 4-1/8" KVP we run with IMAO, you could basically use any length buffer with the correct spacer length. Probably could be said for any AR platform.

I use a Stern Defense BCG with the added center weight left in. About 16 oz total. All the spacer was for was to set the travel in the 7-5/8 tube. Slips inside the spring, makes up about 5/8". I'll shoot a closeup tonight with the spring. I think the issue is short stroking/ slam firing, I played around last night if I was real carefull I could eject and feed the next round without getting all the way back to the disconnector. Probably off the bench the carbine is rigid enough that I get full stroke, but loosly held in the gravelpit enviornment may have made a difference. Like I said above, I yesterday I changed out the 7-5/8 tube and the EA1095 with a 7" tube and an extra power carbine spring, next step down. That was the combo that I staered noticing buffer bumper deformation with the 7.5 oz buffer.

Yes, 4-1/8" 10 oz tungsten. Who makes a heavier one?

Yes, mean caliber, getting 1500 FPS w/ 155 gr pills out of a 16" barrel! Got the KNS pin keepers KVP 10 oz buffer pistol length 4-1/8" spacer in to set the travel to .125 +/- past bolt lock. 7-5/8 tube/ EA1095 spring Spacer is a steeped setup to allow correct spring length for and correct rearward travel of buffer. I changed things up this afternoon put the slightly shorter spring and a 7" tube, same as in my AR 40 Pistol. I think I could have had too much spring and buffer, the 7.5oz buffer runs well in the pistol with the 4-1/2" barrel was trying to balance the higher pressure loads and the 16" barrel.
