So, I just picked up my newest Arsenal. I already have a SLR-104UR but I wanted something in 7.62x39. I went down to my local gunshop to compare the SAM7R and the SAM7SF. When I got there they had this on the wall. It quickly caught my attention and asked to see it. I was surprised at the lack of weight the rail brought, it was also soft to the touch unlike a couple of the other ones I've had. One of the best things about it was the fact that it was only a $50 upgrade. I have now shot over 400 rounds and it is so smooth!
I decided on the Trijicon SRS for choice of optic and it is also rock solid!
I would also like to recommend
The Peacemakers Firearms in Las Vegas, NV. Very friendly and knowledgeable staff paired with great prices!
Here are some pics, enjoy!
