Purchased from a gentleman off here in Hopup land. Great buying experience and quality work but ... It's just not my thing on the SD. I like it slick and the original look and feel of the original handguard. Never used. Not sure it'll fit all sd models but can verify it fits my GG SD. All sales final, no refunds, no returns, PayPal only, no local pick-up, shipping only, buyer pays shipping and PayPal fees. Ask questions prior to purchase.
