More secure than the hk mount - UTG Pro Extended Picatinny Claw Mount for MP5 / MP5K

I purchased an HK claw mount for my SP5K and I could never properly torque it down because there was enough deflection that it would pop off from the lugs. It works fine on my SP5 but I needed to find a replacement. The UTG design engages with the lugs more directly and securely. So the HK mount is cool when it works and has the “HK” logo etched on it. But the UTG is lighter, more secure and costs 1/4 the price.
