This is my mtr16. I'm the 2nd owner and I've not skirmished it. I bought it because I loved the idea of a fully ambidextrous m4 but I'm just a bit too trigger happy for a gbbr. The only change I made to it is installing an aftermarket selector switch. I think it's 5ku or something similar. It a lovely gun and shoots very well. Its a bit inconsistent on locking back on empty when I tested it earlier. I'm happy to chrono it if you need me to. 

I'm after £400 collected for this. I don't want to post it but if you need it posting let me know and we can talk about it.

Its comes with one leak free short mag. At the moment I have another short mag for sale on here too in the parts section.
