Lawrence Precision Nexus Compact if you fire a lot of shots or use BT's. atb Tim
Before I bought a mod I did a bit of research and discovered that aluminium mods were according to one manufacturer unsuitable for Ballistic Tips or if many shots were fired in quick succession (eg if you were testing some reloads or zeroing). I understood that this could lead to gas cutting problems. I think that someone may have done a post on this site about it although obviously having got a titanium mod I wouldn't expect to experience the problem myself.atb TimWhy would you need this particular moderator if using BT's?
I assume you mean Ballistic Tips?
