    Another photo after todays session.



    Some quick thoughts.

    1. The rail gets hot. Running a high volume of fire carbine course is going to get uncomfortable fast. At the same time, the rail also dissipates heat fairly quickly due to how well ventilated it is. The slim profile also means that there is simply not all that much material there to absorb heat. Either that or the heat sink barrel nut shroud/mounting collar really is pulling heat off of the rail THAT well. Im not sure as im not an engineer.

    2. The slim profile is awesome, even better than i had anticipated. This deserves mention once more.

    3. The lockup is solid as can be. No wiggle in the rail, ZERO despite the use of a two point sling. We shot from supine today and i generally press out with the rifle just enough to apply forward pressure on the sling to help mitigate recoil and keep the sights in line with my eyes. Zero flex on the rail while doing this and i tend to push with my reaction hand fairly hard for the sake of consistency.

    I am very pleased with this rail and i cannot wait to see how it holds up over time. A little under 500 rounds through it today and no movement on the mounting bolts.

    My only real concern is whether or not this rifle will be suited towards high volume training. I have my doubts but honestly, as a civi, my love of carbines is rooted mostly in fantasy and a desire to practice a skill set that i find fascinating. The likelihood of me needing to grab a rifle is slim to none so for me, this is not a go to war weapon and if the light weight, profile and ease of use works for me the worst case scenario is that i have to don a glove in order to train.

    Thanks again Samson for what i believe to be one of the best tubular rail systems on the market

    Received mine yesterday. Some of the edges are kind of sharp, but it should do well. You don't need 360 degrees of rail space- look at the cost savings of doing it this way with modular rail pieces.

    I'm in the market for a Daniel Defense but the Samson is damn sexy and cheap.

    I like the fact that it uses the factory barrel nut and has two symmetric anti-rotation tabs instead of the one-sided tab like the Troy/VTAC.

    How hot say compared to a quad rail like a Daniel Defense if you've shot one of those?

    I like it. I appears to be a bit "beefier" than the Troy/VTAC rail. Maybe it's just the pics.

    In my experience with Troy/VTAC extreme rails, these low profile tube rails get just as hot as DD rails, but there is nothing insulating you from the hot metal. I used to put XTMs everywhere on my DD rails so I could shoot for quite a while without really getting uncomfortable without gloves. I'd say gloves are a must if you are shooting extended strings of fire with these low profile rails without sections on them for insulating rail covers. I was able to shoot slightly higher volumes with only an AFG and gloves. I shot about 120 rounds with about 1 second between shots before it became uncomfortable with gloves and AFG. Without gloves I was really pushing it to get 90 rounds with teh same rate of fire.

I really do believe that uppers/rails/lowers that prevent the gun from opening completely are adding undue stress to parts that dont need to be stressed in that manner. Im not sure if Samson is addressing this although i did suggest that he radius the FRONT edge of the locking clamp to remove the square edge there and he said it was already in process on production rails.
    How far of a difference is there shotgunning open as compared to non-tube rails and a stock HG?

    I like their optional extension. I'd like to see that for Troy TRX.



    BTW, what's the OD of the tube?

    Slot cut down the middle of the add on rails is unacceptable.

    The S cooling slots are a bit of a disappointment in terms of using them for mount-n-slot type things. Looks (just from the pics) like it would be harder to keep things in place (??)
