It's here! I'm 110% impressed! Ben is an artist in ARs. But the DPMS lpk in my Spikes lower is junk. It's like a $2 saddle on a $500 horse... just doesn't do it justice. The trigger has a mile of creep and the bolt stop button is so bent that it catches on the bolt so badly that you can't get the charging handle to move 1/2in before it catches the bent button and makes hit the upper and stops the bolt from traveling back. I removed the bolt stop and tried to massage the button out enough to allow the bolt to move without the button striking the upper... as you are probably are aware... cast aluminum doesn't "bend"... it breaks. I had to grind off 2/3 of the button just to get the bolt to move freely. It makes it a pain in the ass, but at least I can get the bolt to cycle now. It'll work till the new one I just ordered to get here. The Spikes is great, the Bison is outstanding, but the DPMS is impressively bad. I hope to get a few rounds down it tomorrow. But I'm not expecting much till I can give her a good trigger,and get a propperly cast bolt stop. A huge thanks to Ben! He turns out a great product! And a huge F U to DPMS for making such a poor parts kit.
