Thinking about building a new AR platform, just want some input/suggestions. A friend is offering me $650 for my current rifle (DelTon DT Sport, full magpul MOE, BUIS, UTG red dot). I want to use that money to upgrade to a better system, but still keep it under $1k. Here's what I'm thinking of going with... PSA 16" M4 premium Chrome-Moly barrel, 1x7 $379 http://palmettostatearmory.com/inde...mv-cl-upper-with-bcg-and-charging-handle.html Spike's Tactical stripped lower ($80 from local gun store) PSA lower kit $130 http://palmettostatearmory.com/inde...parts/build-kits/moe-lower-build-kit-fde.html Spike's battle trigger $60 http://www.spikestactical.com/lower-parts-spikes-battle-trigger-p-425.html Spike's ST-T2 heavy buffer $38 http://www.spikestactical.com/lower-parts-spikes-stt2-heavy-buffer-p-201.html Accessories to include a Magpul handguard ($25), Blue Force Gear VCAS, SureFire G2X Tactical on a Magpul Rail Light Mount, Magpul BUIS, BAD lever, Vortex Strikefire ($100) red dot, and a YHM Phantom aggressive muzzle brake. I already have all accessories except the red dot, going to pick it up this week, and the handguard. The total comes to around $800 without taxes or shipping, so I still have some room to play with. What do you think?
