Many parts in a well laid out webshop. Competitively priced and many parts you can't find elsewhere. If you're looking for that one part to finish a build, this has been the 1st choice for me.
Tolerances are a bit off. Has some significant wobble and bolts on with a single point. But good for the price.
Ordered the handguard, was despatched really quickly, well packaged. Contacted customer service in regards to a query about the part, they responded within a few hours and have rectified the query.
If you have any doubts about ordering from sixmm I wouldn't they have done a great job & they are easy to do business with.
Thanks
My install was complicated with fixed bayonet lug in the way, took some fitting. Just happy that threads matched up with parts mk12 can.
Fast shipping. Matched up with mount provided and fit correctly, more than I can say for evike.
