ACTION ARMY AAP-01 200MM TIGHT BORE BARREL by Action Army

The Action Army Silver Streak 200mm precision inner 

barrel is for extending your original 129mm barrel 

inside the AAP-01 suppressors when fitted on 

the end of the original outer barrel. 

Alternatively, use the AAP-01 Receiver Adaptor to

replace the outer barrel and have the inner barrel run

right through the suppressor! This will most certainly 

increase your accuracy and range, especially if installed 

together with the AAP-01 upgrade hop unit. 

These precision inner barrels also work perfectly fine with the 

original factory fitted hop unit inside the AAP-01/

A tight bore barrel noticeably increases the accuracy of 

your AEG over the stock barrel so you will get tighter shot groups. 

Since the barrel fits tighter around the BB your compression will also 

increase which can boost the guns velocity by 10-20 fps.
