Tribus enhanced castle nut - Strike Industries AR Enhanced Castle Nut / Extended End Plate

I recently got my Tribus enhanced castle nut in Fde. I love it.... Ill be honest tho. I have a Sig Sauer tred ar15 .223. the magpul endplate i had previously did not allow for removing the sling if the butt stock wasnt extended. So i got the Tribus to replace it. Firstly. The long castle nut would not allow enough room for the endplate to thread in deep enough to hold down the buffer spring indent and spring. It was maybe 2 threads short. So i happened to have an additional FDE castle nut in the regular size and had to use that. Strike industries needs to look into that. Cause it would have been nice to have what was actually pictured. But it looks good. With the old nut.
