Great replacement buffer - JP Enterprises Silent Captured Buffer Spring, .223 With Weights

This is an awesome replacement buffer for any custom ar build. It takes a lot of the spring noise out of each shot. The bolt comes back smoother and much more controlled then a standard ar spring and buffer. Be sure to remove the buffer detent pin. You can put it in with out removing it but it makes it a pain to take out for cleaning. The grooves on the weight will get stuck on the detent pin and it will take u a while with a flat head screw driver to push the pin down, as I had to do. So be sure to remove the detent spring and pin. I would highly recommend this product to anybody wanting the best for there gun. It really did make a difference. I'm running it in a 2 Vets Arms 300 blackout, with no problems.
