Top 5 Stripped Upper Receivers        

                           
Best: http://www.rainierarms.com/?page=sho...roduct_id=1611 (tighest specs in the industry, no other upper receiver is even close to being machined so perfectly)

second: http://www.rainierarms.com/?page=sho...product_id=461 (very tight tolerances, just not as tight as Rainier)

Third: http://www.bravocompanyusa.com/Produ...%20LT-007%20M4 (the BCG moves smoother in these receivers than any other I felt)

Fourth: http://www.rainierarms.com/?page=sho...roduct_id=1814 (just a fine Billet upper with exellent barrel fit, just not as tight tolerances as the ones above)

Fifth: http://www.rainierarms.com/?page=sho...product_id=189 (my favorite forged due to best barrel extension fit I've ever seen on a forged receiver)

everything else is pretty much equal, even Noveske receivers are just branded CMT receivers made to mil-spec dimensions.

Thanks for the message, but I did not like the spider.

链接失效了，如果我猜的没错，第一是ultramatch，第二是vltor

不过我觉得这俩没什么区别

BCM blem我也有过，感觉比PSA的略好有限

打算弄个spike试试看
