New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

Introducing the Polarstar UGS Stock Rail - the perfect accessory for customizing your UGS stock for the ultimate tactical advantage. Made from high-quality aluminum, this rail provides indexing and length adjustment that you would normally expect from a rail on a buffer tube. By simply swapping out the rails on your UGS stock, you can easily configure it for use with Milspec CO2 inserts and Milspec stocks, giving you the flexibility to customize your weapon to your specific needs. Please note that all UGS stocks for M4 models use the "Original" rails, while all UGS stocks for HK417 models use the "R01" rails.
