Gas vs mass tuning?

I was thinking a well tuned AR15 should cycle 100% with the minimum amount of gas needed (from adjustable gas block) right? So shouldn’t you always pick a low weight buffer and then turn down the gas on gas block? How’s that effect the cycling compared to a heavier buffer with more gas? How’s recoil impulse change or does it? The only difference I see is with lighter buffer and less gas it would run cleaner…… are the principles the same when suppressed?

Light buffer + lower gas = ?
Heavier buffer + more gas = ?

Are they equal??

Firearms Several of my guns for sale - Prices DROPPED

Just looking to punt the last of the guns I never shoot anymore. I can get better pictures of specific items for serious buyers so I don't clutter this entire post with photos.

Left to right:

1) Armalite SPR-1 AR-15 in great shape. This is the monolithic upper version that they put in the running against the Bushmaster ACR back in the day. You'll find other SPR-1 lowers but with a regular drop in handguard upper. This one is a little more rare and pretty sweet piece to add to your safe - $800 shipped

2) LMT MARS-L lower with Larue trigger, Larue upper with a Larue pencil barrel and a Geissele handguard. Sort of a RECCE-ish build that has just sat in my safe for a while. - $1,000 shipped

3) Dickinson semi-auto 12 gauge duck/goose gun. - SOLD

4) Components ready to build. - SOLD

5) Stoeger Condor Supreme over/under 12 gauge with 26" barrel and interchangeable chokes. I kept this around to have a cheap upland/sporting clay gun but hardly touch it anymore since I upgraded. It's a little goofy because the safety will kick on between shots. I messaged them and they were willing to look at it although it's outside the 5 year warranty, but otherwise I was just going to do a safety delete on it anyways. Great condition and maybe an easier fix than I think - $275 shipped

6) MPA built 6mm creed. The action is on its second barrel so there's around 1200 on the action. The barrel is like new and has less than 100 rounds on it. 1.250" straight, 26", 1:7.5 twist barrel. Has a TT trigger. It sits in a KRG W3 folder and will come with one magazine. I am keeping the optic that is on there. - $2,100 shipped

7) (Not pictured) - Glock 19 Gen 3 with an Agency trigger - SOLD

Trades:
- 6mm CM, 6.5 CM, 7 PRC, or 308 match ammo
- 7 PRC heavy SS barrel for a Defiance Ruckus
- 338 Lapua Ammo
- DBAL, PEQ15, or similar. FDE preferred.

SOLD Sig M18 w/ Romeo Pro 1 + Herrington Arms comp, Streamlight TLR1s and 2 holsters

So I have an excellent condition Sig M18 9mm. Has a Romeo pro one red dot which is also in excellent condition with clean glass.

Currently outfitted with an Sig factory 3.9” threaded barrel and a Herrington arms compensator HC320XL installed. OG barrel included.

Comes with an excellent condition Streamlight TLR1s WML and two holsters.

Both nice kydex options for carry. A C&G OWB and a Hellhound Arms IWB. Both are made to fit gun with WML and compensator.

So I only have two mags one 17 round and one 21 rounder so know your laws.

Not exactly sure how many rounds have been shot through it. I bought it used off GunBroker recently. It’s lightly used for sure, I would say definitely under 500 with the original barrel. And with the threaded barrel and comp, I’ve only put another 100 at most. Both were bought new.

Comes in factory case with paperwork, etc

Asking for $675 plus actual shipping from FFL to your FFL. Venmo or PPFF.

Trade for a custom bolt action receiver or barreled actioned, like a zermatt origin/TL3, ARC CGG , or Aero SOLUS or ?? Something I can use for a long range bolt action for steel/comps?

I’m on the fence about what caliber I really want to go with right so I’m open to hear offers. Cash added were needed

Or

New/ newish Vortex radian carbon fiber tripod with ball head
