This is a magnetic "Ball" detent that is adjustible in terms of travel and pressure. It has a faster return rate than spring based detents and it uses a cylinder with a domed end A.K.A. a "piston" rather than a ball. It also has a very low friction coeficient. The design allows the detent to go into the chamber further without interfering with the bolt, which means you can get a stiffer setting without problems and less multifeeds even with forcefeed loaders and High CPS.
It is also rebuildable, but that is unneccesary. and because the externals are made from the body and a screw in cap, they are available in whatever color combo's you want to match your gun, or raw for custom jobs.
The Kila Products V2 Magnetic Detents are newer, so they should be commonly available, both new and used.
I lost a the delrin once they replaced it and then I wore one down so the sent aluminum ones for FREE no questions asked - each time at their expense. buy these with the new aluminum design - rubber and delrin wears down over time aluminum will never. they make the best detents
top notch. I would buy these again anytime - quick response time and spent at leads $15 shipping to me both times.
Uses angel threads. Too long, some modding required (easy)
Before I used this my marker was double feeding consistantly with the force fed hopper. It now requires more than just gravity to drop the ball into place the balls must be forced (#3/#4) into position. Note: I had to modify the length of the detent and adapter (easy). I am sure they will come up with the right length as time goes by.
Buy it. It works.
I have been dealing with Kila directly, very accomidating people. Easy to communicate with. I look forward to seeing more products from them.
