Is the bottom rail on the sub 2k a picatinny rail

My son wants to buy me a flashlight laser sight combo for my 2k to mount underneath the barrel. He asked me if the rail was picatinny or M-lock. I thought Picatinny but decided to ask you guys. Also any suggestions for what kind I should get

@IrishDeacon It’s a Picatinny rail on the bottom and top. M-lok on the sides.

I like the Streamlight TLR-4 mainly because it can be screwed on and unscrewed quickly by hand, no tools needed. I just don’t need it or want it hanging off the bottom when I’m only target shooting.

@IrishDeacon Hey Art… as another recommendation is the Olight Baldr. Seconds to mount and unmount. And allows for side mounted M-lok bipod legs. Also I can quickly unclip and add it onto one of my several Glocks. And with 1350 lumens you will blind an intruder, no need to fire the weapon. lol.

I also run a BALDR Pro on the lower Pic rail of my Sub 2000.

Baldr Pro advantage is being powered by two batteries - longer life. It is great for a carbine.

Hey Keith… I really love it…



Thanks for the quick reply. Does the 8” high one work ok or would the next taller one work better?

The one pictured above from Amazon by UTG is telescoping (and easily adjustable) from 5.7" to 8". It’s the one I have and I am sure you will like it.

@TexasEskimo Cool setup! What Sling are you running?

@00Buck I have had it for a few years and the tag fell off. I am fairly certain it is the Magpul MS3 (not the MS4 for sure). I think. Lol.

And make sure you take a wide flat file and file the tops of the blocks FLAT.
The fore arm is a KelTec 420 forearm. For less than $100.00


While they are made for the Gen1 and lock into the front of the hinge they can be made to work for the GEN2.
If you look closely the upper and lower rails are staggered The top being closer to the hinge, with the bottom going forward. gives more acreage for mounting stuff. It is very rigid and light !

THe Nice thing about having a rail mounted rearward of OEM is it gives a good base(for eye relief) for a scope
