| I've owned an AR180 B for a while and it doesn't have a good trigger. Has anyone installed a drop in trigger? |

The AR180B should use standard AR15 fire control parts. It was one of the big improvements on that particular platform. You should go to BigRix's website AR180.com and contact him to confirm the B FCUs compatibility. He is a big AR180 fan. You should be able to install better triggers if I remember this correctly. I am only basing my information base on my NodakSpud AR180B replacement lower. |
