I'm not a fan of visible lasers on rifles but that is a personal thing. I keep lights simple with only on and off settings along with ability to get a momentary on. Other than those minor opinion nits. It seems like a good utility piece.
You could have trouble with the stock saddle and your charging handle, and I try to keep optics on the receiver. I like to just keep the nice solid mounted standard front sight, but if you go with a gas block mounted sight, remember that Magpul does not recommend them for gas block mounting because heat will melt them, and they are the wrong height. I like the YHM gas lock with folding front sight if you are going to stay with carbine length rails. If you go with a lo-pro gas block you could put a longer free float railed handguard on there and gain more real estate and get your support had out a bit further to drive the gun. Just food for thought.
Yeah the laser is more for fun than anything. Shooting tannerite at 50 yards from the hip is a blast. I'm not a big fan of gun mounted lights either. 90% of the setup is for display purpose to show people what I can build them. I like the idea of the longer rail I may go that route.
The saddle is well clear of the charging handle and was just spare parts I had kicking around. I'll probably take it off once I have another display gun. Kinda nice to have the extra storage though.
Thanks for the heads up on the front mbus. Heat issues didn't even cross my mind.
I don't need No stinking signature.
