TFB has a really good write up with most of the new advancements: <a href="http://www.thefirearmblog.com/blog/2014/01/14/dpms-308-gen-ii/" target="_blank">http://www.thefirearmblog.com/blog/2014/01/14/dpms-308-gen-ii/</a> Rather than restate that, I thought I would do a quick write up of my limited experience with the rifle.</p><p></p><p></p><p>The first thing I really noticed is the weight. It is noticeably lighter than my 1st Gen DPMS LR. I never would have considered hunting with one of these rifles, but after feeling how light the SASS is, I can only imagine how well the Hunter model feels. A second one of these may be in my future. The barrel on this SASS is fluted and in what surprises me the most, features a mid-length gas system. I am not sure why DPMS did not go with a rifle length system, but they didn't. The weight savings on the GEN II is nice, but it wasn't enough for me to shell out a large amount of cash...until I saw the bolt and carrier. The carrier has serrations cut into it for the forward assist, unlike the GEN 1, the forward assist actually works. The carrier key is installed with a roll pin with the body being machined as part of the carrier itself. The major update that DPMS is touting is the dual ejector and new extractor design. Admittedly, I have had good luck with my GEN 1. It never exhibited extractor problems, well, when the extractor wasn't broken. I have only ever broke one, but after replacement of that one, I hadn't had any problems. Unfortunately, others have had many extractor related issues. The new GEN 2 extractor design should eliminate that. I have only shot 230 rounds through the rifle so far, so it will need much more testing to lay that issue to bed. I changed the trigger out to a Geissele SD-E. The stock match grade trigger is actually very nice. It has just a little bit of creep in it that would probably 'shoot out' with some rounds through it. I just switched to the SD-E Geissele because I like them. I also ditched that awful grip and palm-swell for a stock A2 grip. I just think the thing looks hideous and doesn't serve any purpose. Lastly, I added a Slash's 10oz Heavy Buffer from my Gen 1 since I knew I would be shooting this rifle suppressed.</p><p></p><p></p><p>Dual Ejectors:</p><p><a href="http://s1171.photobucket.com/user/drewjordan/media/20140404_143133_zps38eece4b.jpg.html" target="_blank"><img src="https://www.okshooters.com/data/MetaMirrorCache/i1171.photobucket.com_albums_r554_drewjordan_20140404_143133_zps38eece4b.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a></p><p></p><p></p><p>Bolt Carrier compared to an M16 Carrier:</p><p><a href="http://s1171.photobucket.com/user/drewjordan/media/20140404_143117_zpsbbfe545b.jpg.html" target="_blank"><img src="https://www.okshooters.com/data/MetaMirrorCache/i1171.photobucket.com_albums_r554_drewjordan_20140404_143117_zpsbbfe545b.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a></p><p></p><p></p><p><a href="http://s1171.photobucket.com/user/drewjordan/media/20140404_143041_zps2e18db9a.jpg.html" target="_blank"><img src="https://www.okshooters.com/data/MetaMirrorCache/i1171.photobucket.com_albums_r554_drewjordan_20140404_143041_zps2e18db9a.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a></p><p></p><p>I shot 30 rounds of my reloads for group.

A suppressor can make a semi-auto rifle do some strange things. I wanted to know if the gun would run well suppressed. While loading a mag, I dropped it feed lips down into the dirt. I thought to myself great, and then I just decided to go with it. I ended up putting a couple of handfuls of dirt directly into the magazine. I figured the dirt and suppressor would highlight any of the rifle's weaknesses. I chambered a round and shot 20 rounds without a problem. At this point, I figured I needed more dirt, so I put some dirt in the magazine and then directly into the chamber. I then shot 20 rounds as fast as I could pull the trigger. It just ran. This is obviously not a scientific test, but I really thought the dirt and suppressor would cause something to malfunction, but it didn't. I dusted the magazines off as best as I could and continued to shoot. The last 60 rounds I fired as fast as I could. At the conclusion, most of the SLIP 2000 EWL was burnt off and the can was smoking hot. No malfunctions.</p><p></p><p><a href="http://s1171.photobucket.com/user/drewjordan/media/20140404_114804_zpse12bb0d4.jpg.html" target="_blank"><img src="https://www.okshooters.com/data/MetaMirrorCache/i1171.photobucket.com_albums_r554_drewjordan_20140404_114804_zpse12bb0d4.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a></p><p></p><p><a href="http://s1171.photobucket.com/user/drewjordan/media/20140404_112524_zps5168d583.jpg.html" target="_blank"><img src="https://www.okshooters.com/data/MetaMirrorCache/i1171.photobucket.com_albums_r554_drewjordan_20140404_112524_zps5168d583.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a></p><p></p><p>I had one issue with a piece of factory ammunition.
