Review: True to size - Just what we needed true to size good quality
Review: Great barreling for nerf blasters - This product review is for Round Brass Tube 9/16", Carded I used this brass tubing as part as an experiment of mine. I really wanted to see how hard I could possibly make a nerf blaster shoot with optimized internals. I used this, as well as K&S Engineering's 17/32" brass tubing to create a breach for one of my nerf blasters. It had a perfect fit around the foam dart and held up very well under high pressures of air. The overall performance of this tubing is very high, as I am getting speeds over some airsoft guns with a nerf blaster. My project wound up shooting the foam darts over 300 feet per second, and sometimes it was limited by the darts' durability alone. As a barreling material, this is a very high quality product and I would highly suggest it to others looking to use it for a similar purpose. It also came with a gratuitous amount of padding when it was shipped. I can only assume that this was to prevent any potential defects in the tubing during the shipping process. To me, it showed that the seller was determined to deliver an unharmed quality product to their consumers even if it meant going that extra step to ensure the product's safety. Overall, I would highly recommend both the seller and the product to anyone thinking of purchasing it.
