TM Hi Capa 5.1 Barrel Mod

Earlier in the week I dropped by ASC Armoury to pick up a few parts and Carl showed me the work he did on his TM Hi Capa 5.1. Specifically he got rid of the barrel wobbles (inner between outer and outer between slide) and was telling me how it dramatically decreased grouping size.

He machined custom shims and his results were definitely excellent, I witnessed them first hand on Friday. 😉 Anyway I don’t have the skill, know how or tools to make myself what he did but I do have a lot of electrical tape and patience. 😀

Yes it’s crude but the results are rather surprising! At 6 meters groupings after 10 shots are within 5 cm!!! Note one shot was taken every second I didn’t spray the area but then again I didn’t have time to fully set either, that’s what makes the results so surprising!

Unfortunately I didn’t test how the gun performed before the mod. With the tighter inner barrel, the gun performed pretty well but not up to this level for sure. I can’t wait to try the TM Hi Capa 5.1 in a game situation. 🙂

  1. hi, i was wondering how you were able to get a hold of a tight barrel for your hi capa 5.1
    also, what are all the mods available for the hi capa 5.1?
    can one make a silencer for this pistol?

    i would love to hear from you, my email add is daddyairsoft@gmail.com
    thanks!

  2. Hello.

    You can get a tightbore barrel at any of the major retailers, I got mine from Redwolf but you can go to WGCShop, etc or ask your local retailer to get them for you. Yes you can attach a silencer to the Hi Capa 5.1 but that would require a metal outer barrel which supports this. Again it can be had pretty easily if you go to your airsoft retailer.

    Hope that helps.
