This place has been great to get ideas from - thanks for all the great feedback I've received since becoming a more active poster. I have a beginner Anderson MFG AR15 (AM-15) multi-cal that I'm just starting to put some updates into. Thus far I have put the quad rail hand guard on so I can prep for a tactical light and hand rail, the Bushnell Trophy TRS-25 Red Dot and Magpull MBUS Gen II backup sights. I talked to a local gun shop and got some ideas but now I'm hoping for some references to a good choice in tactical flashlight, hand rail and even grip replacement. For flashlights I'm looking at a couple options on Amazon. UTG Defender Series: http://www.amazon.com/UTG-Defender-..._m=ATVPDKIKX0DER&pf_rd_r=1DCF9Z7YE33Y48KQXDN8 And the smaller Streamlight: http://www.amazon.com/Streamlight-6..._m=ATVPDKIKX0DER&pf_rd_r=1DCF9Z7YE33Y48KQXDN8 Does anyone have good suggestions on tactical lights? I think (without experience) I'm leaning towards one that doesn't have the hand grip attachment for activating the light.
