Very nice finish, excellent fit. I like the pin locations have dimpled centres, makes drilling that much easier. Having both the HTX and Nefarious I prefer the latter.
Let customers speak for us
from 26 reviewsHelps immensely when pushing pins. Keeps everything stable and easy to work with. Keeps you from marring your barrels!
Gives me the confidence to work on my 416 platform gun without damaging anything. Works on multiple platforms as well.
Folding sight arrived in great shape. Works with my 33mm height rear just fine. A+
Awesome tool! Its well made, helps with working on yhe 416 platform specifically. Great finish too.
Same ol’ great NA quality we’ve all come to expect. Super cool threads!
For those who don’t already know, you CANNOT do better than Marvin’s barrels. Or pretty much anything Marvin makes. Spend some money, buy his stuff, own great sh*t.
Quality item. Machine work is flawless. Best HK barrel you can find brand new.
Great hard to find unmarked HK upper. Super fast shipping too!
No issues with installation. Was easy to just, just took a little time to try the different jets. You need to make a version for the MR762.
It is nice to do business with a company that provides impeccable customer service along with quality products. Very happy with my purchase of the HK 416 reaction rod.
It's always nice to have the right tool for the job. This reaction rod is precision made from quality materials and meets HK's exacting tolerances without damaging the barrel.
So far so good. Fits great! Great products! Been running there barrels for a couple years!
