MR920 Elite with the lightening cuts and top serrations. Has a bronze Radian Ramjet, Radian RSA with a couple different springs to tune it to your preffered load, Holosun 507C, and a TLR1 on it. I can sell it as is, completely stock (original barrel and RSA), or anywhere in between. Its been 100% reliable with and without the comp, shoots extremely well and is an awesome carry gun. Got my other gun ready so just looking to sell this one. Thanks for looking!
