Stock loose fit - JE Machine Tech AR15/M4 .223 MIL-SPEC 6 Position 3 Drain Hole Lightweight Long Contour Machining Fluted Buffer Tube w/ Circle Cut Out On End Cap

This tube is very light weight and good quality finish. Mounts solid to lower r. The fluting looks great with my light weight Faxon heavy fluted 20" bbl. But because of the fluting my MFT minimalist ultra light butt stock fits loosely. A piece of Scotch brand black electrical tape under the butt stock filled the space and now does not wiggle. I'm not sure you can have a fluted or other light weight buffer tube of this kind without a slightly loose fit from b. stock. A non critical compromise for light weight build and easy fix IMO. I give it 4.5 stars.
