Sent my USP Compact in for an RMR cut and received my finished product in a week. The job was done quickly and precise, I couldn’t be happier. Big thanks go out to ZR Tactical and I’ll be sending any future HK slide work to them as well.

Fast free shipping for the holiday, fair prices.

great item at a reasonable price.

Highly recommend it’s very good quality at fair prices

Very well made product and has most definitely made shooting my GSG better. Just feels more robust than the factory plastic and longer guide rod. I cannot get any parts here as I live In Melbourne Australia, ordered the Ultimate package in March 2021 and it took a month to get to me. Well worth the nervous wait. Thank you very much for a super product.

Excellent fit. Shipped on Friday, received the next Friday (USPS priorty mail both ways). Couldn’t be happier! Thanks!

These things are absolutely wonderful. Super easy to install. Remove stock base pad with any type of punch or screwdriver, I used a really fine flat head for a few reasons. You’ll need it to pop out the spring from the plug that needs to be taken out. And when sliding the ZR pad forward it can depress the detent and slide past the lip of the magazine much easier.

This is a 20 and 30 round with the pads in HSGI extended pistol TACOs

This was money well spent. It was easy to install. And no more take down screw. And the pistol shoots better now.

Firing Pin, main spring goes in no problem. Sear spring is shorter than the original in my Sig 1911/22 and cannot be use. So far the indentation on the snap cap shows a stronger strike by firing pin. Looking forward to this weekend to see if this will solve my issues. Also had the ultimate kit installed a year ago.

Shipped amazingly fast. Super responsive customer service. Product arrived within a few days and was exactly as described. Impressively tight fit to the ZR9 80% Lower I ordered along with it. This was my first experience with ZRTS and it couldn’t have gone better. Would highly recommend doing business with them.
