Frequently Asked Questions:

Q: Why is the Lambda One AEG tightbore barrel more expensive than other tightbore barrels?

A: The Lambda One Airsoft AEG Tightbore Barrel is a precision-machined barrel made in Japan. It stands out in terms of quality and accuracy due to its extremely tight tolerances. With a tolerance of 1 micron (equivalent to 0.001 millimeters), this barrel offers unmatched precision and performance.

Q: Why use a 6.01mm inner barrel as opposed to a 6.03mm inner barrel?

A: The 6.01mm inner barrel provides superior accuracy compared to a 6.03mm inner barrel. While it may cause a slight decrease in FPS in certain guns compared to a 6.03mm tightbore barrel, it still offers better FPS than a standard AEG barrel (ranging from 6.05mm to 6.08mm). The tighter inner diameter ensures better air seal around the BB, resulting in improved accuracy.

Q: What guns will the Lambda One Airsoft AEG Tightbore Barrel fit in?

A: The Lambda One Airsoft AEG Tightbore Barrel with a 6.01mm diameter and TM AEG barrel cut is compatible with a wide range of AEGs (Automatic Electric Guns). It is specifically designed with the W groove cut for TM M14 chambers.

Q: What length barrel do I need for my gun?

A: The appropriate barrel length depends on the model of your gun. Here are some common lengths for specific models:

Model Barrel Length
PSG-1 595mm
M16A1 & A2 / AUG 509mm
AK47 + S / SLR105 455mm
M4A1 / SR16 / SIG 551 363mm
M1A1 / M733 303mm
G36C / SIG 552 / P90 / CAR15 247mm
MP5 229mm

Q: Why upgrade to a tightbore barrel?

A: Upgrading to a tightbore barrel offers several benefits, including improved accuracy and FPS. Aftermarket tightbore barrels are precision-machined with better fit and finish compared to factory barrels. The smaller inner diameter (ranging from 6.01mm to 6.03mm) ensures a better air seal around the BB, leading to increased FPS. Additionally, the precision machining of tightbore barrels ensures smooth passage of the BB, enhancing accuracy and minimizing groupings caused by imperfections.

Q: How do I install a tightbore barrel?

A: The installation process for a tightbore barrel may vary depending on your specific gun model. Generally, you will need to remove the hop-up assembly, which houses the inner barrel. After that, you can turn off the hop-up and remove the barrel clip to replace the barrel and bucking. Finally, reassemble the hop-up assembly and ensure proper installation. If you are unsure about the installation process, we offer a gun repair service on our website (link). Choose the "light" service level and send us your gun and barrel for professional installation.
