i am currently awaiting my tax return to buy my ar kit and lower. well i decided to go to my local gun store and see if they have any stripped lowers. The clerk told me that they currently have DPMS stripped lowers for $130.00 which to me seems like a descent deal. i then told him that i was planning on putting it on a del-ton kit and needed to know if they fit well with other AR rifles and not just DPMS rifles. The clerk then told me that a lot of companies contract out to one big company for their receivers and just put their own stamp on them... I dont know enough about AR rifles to argue with the clerk so i just took his information with a grain of salt. surly this isnt the case is it? i am wanting to put this DPMS lower on a del-ton m4 kit, but i really dont want any slop(not that much anyway) on the gun, i was originally going to buy a Spikes Tactical lower for $100 but after dealer transfer fee and shipping im looking at $140 roughly, plus i want to support my local gun store as well. so with that is the DPMS lower any good?
