Works great, with a little fine tuning. - MFT E-VolV Picatinny Rail 2.205" for Standard and Thickened Heat Shield

The piece arrived much quicker than expected, Especially after reading reviews about the site. Over all the piece worked great though like others it was slightly thicker than my factory guards. Simple solution was to use a fine grain sand paper to lower the plastic till it was just below flush with my guards. I also had to do a little sanding on the edges it get it to sit properly into the groove. Now the piece fits nice and snug and I haven't noticed any slippage, yet. The instructions state to remove the heat shield so not sure why one review says you shouldn't.
