Great customer service, dispatched and delivered on time.
Product: for the price absolutely outstanding, seen much more expensive products, the stock I received is virtually the same to look at can't comment on quality of the other products but I am very pleased with the quality of this stock from Sixmm. Folds down very easily with a very secure mechanism and looks great and operates perfectly. 10/10, fully recommend this product.
Awesome service and product as per usual!
Good Bolt Release BAD Lever
This thing is compatible with APFG SIG MCX Virtus Legacy GBB.
Fits the marui hop up chamber perfectly and factory slide aswell.
I also tried it with a TTI hop up chamber and an EDGE slide which both fitted really nice. The finish is a brushed silver color which is not polished.
