| What's involved in installing a FF RAS? Do you have to remove the barrel? |
|
Quoted: No you do not have to remove the bbl or the front sight post. The RASII splits into two pieces. It would help to have another person there to help, but I managed by myself. Actually, the FF RAS does require disassembly of the barrel. However, you could go with the RASII like bvm mentions because it does not require disassembly. |
| On two Colt barrels that have seen a few hundred shots through them, the front sight tower is all but impossible to remove, the tapered pins are a pain in the ass. I recently bought two new BM barrels with the front sight tower attached, neither would budge. I spent 2 hours a piece cutting them open, wasting two perfectly good front sights [>(] |

I just removed the front sight base from my colt barrel and it was actually a lot easier to do than I thought it would be. Had one person hold the barrel with a front sight base resting on a rubber mallet head. Took a 3/8" brass punch and gave it about 5 good whacks on each pin with a 1 lb hammer and the pins came right out. Didn't even deform the pins any, so they can be reused. Then used a rubber mallet to tap the FSB loose from the barrel. The FSB did have a decent press fit to the barrel, evidenced by the fact that there was no carbon residue deposited between the barrel and FSB around the gas port hole. I have heard that the pins on Bushmasters are much harder to get out though so YMMV. Then again, maybe I just got lucky with this barrel/FSB combo. |
