Out of curiosity I asked AI some gel questions. Feel free to add your own 
Does a tightbore barrel make a difference?
Yes — but in gel blasters it’s a small, conditional difference, not a game changer.
Using the correct gel barrel range (≈7.3–7.5 mm stock → ≈7.1–7.3 mm “tight”):
What actually changes
You may get a slight efficiency gain → sometimes a small FPS bump (often barely noticeable)
You can get slightly better consistency — but only with very consistent gels
The system becomes more sensitive to gel size, hydration, and feeding
What most people actually experience
Many builds: no real change
Well-tuned builds: small improvement
Average setups: more issues than gains (inconsistency, occasional feeding problems)
The key point Tight bore doesn’t “add performance” by itself — it tightens tolerances.
If everything else is already consistent, it can help a bit. If not, it usually makes things worse.
Simple answer Yes, it makes a difference — but in gel blasters that difference is minor and only works in your favour on a well-tuned, consistent setup.
How much spring is too much spring?
Short answer: “too much spring” is the point where your setup can’t complete a clean, consistent cycle anymore — not just when something breaks.
For gel blasters (AEG-style gearboxes like LDT/LX), the limit isn’t one fixed spring rating. It depends on motor torque, gears, battery, and your compression setup.
What “too much spring” looks like in practice These show up before outright failure:
FPS becomes inconsistent (big red flag)
Motor sounds strained or slows mid-cycle
Semi-auto starts double cycling or not resetting
Rate of fire drops hard
Heat builds up quickly in motor/wiring
Occasional lock-ups or failure to complete a cycle
If you see those, you’ve already gone past the useful limit.
Rough realistic ranges (for context, not rules)
Common builds:
M90–M100: easy, reliable, most stock-ish setups
M100–M110: solid performance zone for most upgraded builds
M110–M120: upper end for well-built setups
M120+: where things start getting very setup-dependent
Where it usually becomes “too much”
Stock motor + standard gears (18:1): anything past ~M110 starts to feel stressed
13:1 gears + 25k–28k motor: M110–M120 is usually the practical ceiling
High torque motor + good wiring + strong battery: can push higher, but returns diminish fast
The important part Spring strength doesn’t just increase FPS — it:
increases load on gears, motor, piston, and wiring
amplifies timing issues (tappet return timing becomes critical)
makes air seal inconsistencies more obvious
Why people go too heavy They chase FPS from the spring instead of efficiency.
In gel blasters, you’ll often get better results from:
better air seal (nozzle, cylinder head, T-piece)
correct cylinder volume
good return timing (gel fully seated before release)
A well-tuned M100 can outperform a sloppy M120.
Hard limit reality (gel blasters) “Too much” is when:
the gearbox can’t cycle cleanly every shot
FPS gets worse instead of better
reliability drops off
That usually happens before parts actually fail.
Simple takeaway The best spring is the strongest one your setup can run:
smoothly
consistently
without stressing the motor
