Run M4 mid cap magazines on HPA with your Krytac Vector GBB. 

The benefits of HPA include

• No cooldown effect in cold weather or from rapid firing
• Around 1500 rounds per tank, saving you money on non renewable green gas
• Larger capacity, lower cost magazines 
• Lighter weight magazines

If you need a Tank, Line and Regulator for this adapter, please check our starter HPA bundles here. 

The valve comes pre-fitted. A donor magazine is required for the feed lips and gas router.

Your adapter will come with a number of shims that can be used to ensure snug fitment of your M4 magazine.
