WOW what fun

Written on Apr 14, 2026

I was concerned at first. I prefer to KISS and like the complete drop in FRT's. This went together fairly easy. Used with a RISE 140 trigger. Follow the instructions, Get a H2 buffer. I tried to use an H1 at first but would function consistently. Swapped to H2 and she never fails. It is so much fun to shoot. I used it in a carbine training class and never had an issue with it. I don't know how durable it makes it, but I didn't have any issues with the first 850 rounds. I may end up getting another after confirming durability after 10K rounds. I would definitely buy again.

A bit pricey but wow do you get what you pay for!!

I am blown away by the quality, the fitment of this upper. 1500.00 is a chunk for an upper. You do get the best quality available in a DI gun for this amount though. Bomb proof and will be working long after I am gone. I just wish it had a Keymo muzzle device but that's just a personal preference thing. Surefire does make a hub adapter now at least. I ran 4009 rounds through it when I first got it. I didn't even clean the oil off of it. Ate it all. 55gr, 62gr, 68gr and 77gr. A bit gassy but needs to be for a do it all upper. I will test accuracy this weekend but have no doubt it is at minimum a 1MOA upper. There are claims it is sub-MOA to 500 meters. We shall see. Fantastic buy.

NOT OD GREEN!!!!!!

Part is actually decent. Works great. It is listed as OD Green which was my reason for buying it. It is actually anodized Sprite green and looks cartoonishly stupid. Another part in the junk pile!
