Lightweight, looks great! - Spikes Tactical Lightweight Chromoly Castle Nut

If you have built a few lowers, you probably know how certain parts like castle nuts don't bring the same amount of fizzle as others. I am happy with the quality and I don't see why this castle nut wouldn't hold up to any level of normal use for a very long time. The finish is uniform and certainly adds the little touch that your AR15 friends will be sure to notice. I will certainly consider this for future builds given the price is reasonable. Negligible weight savings for sure, but looks slick! If you are looking to separate your build from the rest, this is a good part for you! Also, STAKE the bloody thing! It doesn't need a huge stake mark either. A small amount of endplate pushed over will be more than enough to keep any castle nut from backing off! Don't be the guy who doesn't stake his nut and loses his rig.
1. Castle nut walks off far enough to allow endplate to separate from lower receiver
2. Rear Takedown detent spring shoots out
3. Takedown pin walks out
4. Upper receiver pivots forward slamming open and bends pivot pin
5. Get the poo-poo scared out of you or worse
Don't laugh... this could happen if you don's stake your castle nut. Just stake it. Its not hard to remove a staked nut if its done like a normal person.
