Is it comparable with a tracer barrel

If I can put a laser on it what kind

It is very well constructed with quality materials it works perfectly straight out of the box the delivery to the UK took just over a month it was held up in UK customs, Zhenduo customer services were very helpful, we have a already purchased more item and there on there way 😁

Well built and work perfectly 😁

The items were dispatched in two packages the first package has arrived with the extra mags and upgrades they are really good quality, shipping was dispatched to the UK within 4 days and arrived on the 14th day i can't wait for Hk416 😁

I gota to say ITS FRICKING AWESOME!

Très content, ce blaster fonctionne correctement. Très bonne vélocité et précision pour le prix.
J'avais peur qu'il fasse trop cheap, mais il n'en ai rien. Je recommande en premier achat

can this be send to the netherlands?

Been 4 days still havent been shipped starting to get worried
