Great looking firearm with good functionality. Would recommend this to anyone
Missing all the of the lpk on this weapon can't do nothing with it waste of money paid full price for nothing...
Bought a Tungsten Slide and Titanium Blue Frame..Love the Kit, Love the Price, and it arrived in the Mail a Day earlier than the tracking stated
I’ve always a thing for building p80s but couldn’t find any to purchase til I came across mdxarms. Very fast shipping and the pricing I will not hold back on purchasing.
Quick shipping, great customer service, super pleased with the product I received.
Every part to get the job done was in the box and the slide was top quality
Great product I love it
I have bought 2 Glock kits from MDXarms.com and would and have told friends about your products. I own online gun clubs and participate in a few others and when asked "Where to buy P80 Glock kits" usually at least 1 or more replies are MDX arms. Keep up the good work.
