Received exactly what I needed with excellent customer service, response time and quality.
Rail is the exact size and is durable. Wouldn’t recommend anyone else.
Delivery time was quick.
Had no issues using these guys at all. Will be returning for more products.
Love buying from these guys, great comm's , excellent service. Keep up the good work : )
Bought some FAL L1A1 LAR magazines from Sixmm plus some other items, as always great service and timely despatch. Thanks guys : )
Does this come with the barrel nut or is that extra and does it fit the VFC HK416D GBB?
