2013年6月23日 · HK/Umarex MP-5 .22. Another AR which is a .22. An AR in .300BK. A Ranch Hand with a buttstock 1 of each? This could be fun. Now I have to do some researching and figure out what the costs will be beyond the $30 for the C&R and the $200 stamp.

2012年2月14日 · To all the AR experts out there, I need some tech help. I purchased my M&P 15 .223/ 5.56 rifle last summer. I have ran around 400 rounds thru it from different manufactures all with the same results.
