Still remains to be the best field in New England. Great selection at the pro shop. They also have online shopping with shipping and store pick up options available. Great admission price and large adaptable field. Perfect for experienced and new players with rental packages available. Unfortunately I wish they have more weekday games available as they are usually only open to airsoft session on weekends but the store will still remain open for your shopping needs. Not to mention they fix and buy used airsoft guns.

Very nice staff, had everything I needed. I would definitely recommend this place to any airsoft players. They have a great field, and overall a great community. They gave advice as what direction to head next with some of my guns and helped me fix issues with my arp9. They had everything I needed in stock for the arp9 and my other guns. Recommend 6/5 stars.
