A new option for you! LESS Php25,000 off from the regular price of any S9-DBB semi-automatic 9mm carbine if you prefer to use your own pair of flip-up sights, handguard, magazine and buttstock. Bring to us your own sights, handguard and buttstock and we will install them free of charge. We have to be the one to install them to make sure the Warranty is not voided. But if you prefer UDMC's standard brands for these parts, we can still install them for you at regular price. Note: Even if you choose the bare bones model, your S9 will still come with the buttstock tube, buffer and buffer spring.
