The quality seems excellent, it shoots straight, the hadguards fit well and to top it all off they cleaned up the pin & weld spot and coated it black so it would not stand out! Colt didnt even do this on their XM177 Retros that were rediculously expensive. Thanks TNTE!
Ordered this barrel for a 177E2 build with one of the new H&R uppers, extremely satisfied with the quality of this product and will continue to do business with TNTE, order was sent out in less than 3 days and arrived in a timely manner.
I finally got this installed on a Bushmaster lower. I took 5 shots to zero it at 25 yards with some Winchester 55 grainers and then I had some fun. I fired 20 rounds as fast I could to test the functionality of the rifle and it ran like a top. I shot 10 more rounds at about 50 yards to test if the zero held and it did. I fired at least 3 more 20 round magazines and not a hiccup in the bunch. The kit is well made; it went together easy and as best as I can tell it works great. It's worth the money. I'll probably be doing business with them again.
