For: Airsoft GI PE 6.03mm Extreme Precision Inner Barrel for E90 (250mm)Product Information:
This tight bore barrel is superb for the price. I installed one of these in my dad's Echo 1 MTC (thats the G36) Clean and very smooth bore allows for really accurate shots and increases range and FPS. Easy to install, if you are new to upgrading airsoft guns, a PE tight bore is a good beginners lesson
But do note, you need to do a few things to make tight bores work really well:
1: Clean them every now or then. If you are using good quality ammo, then the barrel wont gunk up as fast and you can shoot more
2: Use good ammo. Walmart crossman ammo is not bad for stock 6.08 barrels, but they will drastically decrease your accuracy with tight bores. You need good ammo - I recommend G&G ammo... especially .25's in your harder hitting guns.
3: Have a good hop up, often times your stock JG and CYMA hop ups are not even good enough for the stock barrel and cheap ammo... so if your gun doesnt shoot as far as you would like or as accurately, check your hop up.
In the case of the MTC, a new hop up bucking was needed to make the gun more accurate and give it range, the stock Echo 1 hop up was terrible and did not give it enough back spin to make it shoot far
In the MTC, new hop up bucking...
