It’s just big enough for a red dot I wish I looked at the description better for a 120 I thought it would be more but oh well I works great

One of the better low profile mounting solutions for the HK MP5 . Highly recommend.
Solid low-profile rail from B&T. I didn't want to add much weight or mass to the compact SP5 K. This is exactly what I was looking for.
I only use B&T mounts, as they are 'adjustable' for squaring up on the receiver. The HK branded unit with spring loaded levers.. not so much. Plus the HK unit scars the receiver when tightened. Stick with the B&T products.
Mount was easy to install using a level with the SP5 mounted in a gun vice. Great quality and the EOTech doesn't budge.
great product
So far it’s Great
Ordered 2. One fit fine, one did not fit even remotely close. Obviously so type of CQ control with B&T. Either that or these are fake.
Perfect fit and quality!
Good overall purchase.
