Works nice on my replict
I have ordered from this site a few times, most recently an Sig MCX Virtus, very easy process, excellent prices, orders to the UK, no issues with customs, very quick service. Gun arrived without any issues. Will definitely order from these guys again.
Terrible customer service. Item listed on their website are not in stock, whatsapp isnt responded too. Filed a complained with paypal to cancel order and they ignored it and shipped it.
Don't know what actually improves but you know just for pleasure and peak performance 🇨🇱
Perfect fit, peak performance for an AAP🇨🇱
