Flash hider on Bushmaster carbine
I have a post ban XM-15 E2S that I want to put a flash hider on. How hard is it to get the taper pin out? Do you have to put a new taper pin in when you install the flash hider? What do I need besides crush washers. I am pretty good with tools. Do I have a chance or should I just take it to a gunsmith?

I believe such info is on the Bushy website. Or call their 800 number - their customer service is excellent.

Those taper pins can be a bear to remove sometimes. Other times they just pop out. The ones that get stuck are usually stuck due to corrosion. Not necessarily corrosion due to neglect; the pins are a tight fit in the first place and sometimes oil just doesn't get between the pin and the barrel, but humidity does. Use a steel pin punch and a solid strike with a mallet. (Don't pussyfoot the strike, and use a firm grip, so the punch doesn't bounce and scratch something you don't want scratched.)
Instead of crush washers I would use machine washers. Get a bag of washers in varying thicknesses. IMHO, this is the only way to properly index a thread-on muzzle-mounted device. |

cure for stuck taper pins
If you have a stuck taper pin, try using Aerokroil on it. Aerokroil can be ordered from www.kanolabs.com if you cannot find it locally. When I was an A&P (aircraft mechanic) we swore by Aerokroil; it will get anything that is corroded loose. Just spray it on, let it penetrate for 30 min., and the pin should come out easily.
Good luck! |

This is cut and pasted from a post I made on GT:
I thought I would share my experiance because I am sure many will be doing this soon. It started by me trying to find out how the thing was actually attached to my rifle. I figured I could heat it up and wrench it off because I thought it was silver soldered in place, but I was wrong. I went to AR15.com, posted a picture, and asked how these things were put on to make sure, and I got a reply as follows: Quote:
To start, I noticed that the finish wasn't quite "perfect" on the underside of the brake. It was not one of the flat sides, it was the fat, rounded side, so I figured I'd start there... The thing had one "pin" holding it on, but it was far from being a simple "pin" -- it was a set screw. I managed to Dremel around the thing enough to get it off. It took about 1 hr. Some of that time was spent exploring the rest of the thing to make sure there were no more screws. I knew I had the right side though because the cut-off wheel "sparked" differently. I basically had to cut a square around the thing and get it wiggling and then twist it out. It was a pain in the ass to say the least, but, now I have my A2 FH on. Gonna be getting either a Phantom or Vortex soon. Here's a "post-op" pic:
