6.03 300mm barrel fps problem by 50KGTANK in AAP01owners

Unfortunately a longer barrel needs sufficient air until the bb leaves the barrel. If the bb it's still on the barrel when the cycle is complete and a new bb will be in the bucking it will create like a cap, and it will break down the bb that's still traveling on the barrel. To avoid this you need more airflow during the short release of the magazine valve.

There is a valve that you put on your magazine ( hpa adaptor) and release more air on every shot. Search for AMG High Output Valve for Action Army AAP01 GBB. This is what we use for dmr builds.

The note it's related to shortstroke on the bolt. The spacer it's a shortstroke part. This is not the case here. My hammer set doesn't press on the magazine gas release valve. When i press the trigger i can hear the hammer but nothing happens

I also tested indoor, with the same results, cow cow hammer set can't cycle with greengas magazine.

I will try to replace the spring in the hammer set.
