Awesome slide
Favorite slide so far. Looks great, performs well, decently priced
-
Perfection once again!
Love everything I get from these guys and Always get it from 3-4 days of ordering. Can’t find that anywhere else. Their RMR Cut slides are super clean and by far my favorite slide. Only thing I personally like to change on any build of mine is the guide rod, I like those heavy tungsten performance guide rods, feel like the ones that come with ant build from anywhere are a little flimsy but that’s not a knock on MDX, just my personal preference. This place has been the only place I’ll do a build from once I found them. The customer service is great too! Thank you guys

Absolutely love this slide
Again, thank you to the MDX team for being on top of things and for the great customer service. This slide is really a great slide, not going to lie, I haven’t been able to stop staring at the thing, I just think it’s super clean and the slide/parts themselves are very good quality.

MDX G19 LF19 Slide with RMR cut
#2- MDX handles business. PERIOD. they pack it Right & ship it FAST! #2 the LF19 slide is so much nicer than a rock slide(i own 2 of those) barrel & all included parts were included,up to spec, and installed without issue. #3 i installed a holosun hs507c onto the slide without issue and the fit an finish of the cut we exactly as they should be. Thanks MDX. Nice kit for a good price.
