Strike Industries has two very interesting products coming out this year.
First up is their drop in rail for Glock frames. It adds 2 more slide rails giving the Glock frame 6 rails for improved slide to frame fit.
Here you can see the SI frame rail on the left and a factory Glock frame on the right. No information at the moment on cost or release date for this.
Next up is the SI XR. It is a new AR Upper they will be selling as a kit. It is a monolithic upper that is piston driven. You just need to provide your own barrel and bolt face. It has a forward folding non reciprocating charging handle that can be swapped over to the right side of the rail. Estimated MSRP is $700. ETA is late 2015.
