Answers.. Or at least some opinions. Looking at the mark 1 and the 930 spx. I know it is an 18 vs 22 inch barrel, but those are the ones that have piqued my interest. I have a few questions though. What would be a good price on the SLP? Is the SLP worth the price difference over the 930 in terms of quality and reliability? If I had all the money in the world id probably get an m4, but i dont. Used M1 super 90 and used m2 not out fthe question, but im leaning gas over inertia due to the recoil diff. Last but not least, happy veterans day to all the retired and active duty service personnel. Thanks for serving this great country! Wanna kill these ads? We can help!
