I didn't buy the right size, if i did it would have worked wonderfully - UTG Pro Recon Flex M-LOK Bipods

I have a bullpup rifle so I don't have a lot of real-estate for attachments and this would have helped clear up space for a foregrip getting the bipod out of the way. I wasn't paying attention to the length of bi-pod I purchased and the legs for me came too far back when they were folded up and interfered with my charging handle. If I ordered a smaller size from the word go this would have been a perfect fit.

I didn't get a chance to test these out aggressively or shoot with them on but they seemed to be good quality and stable for the short period I did have it on the rifle.

It does take up two entire m-Lok squared so you're losing 4 in total, 2 on each side. I could see that getting in the way if you had a lot of attachments on your rifle but that is so person specific that I don't really see that as a problem at all. If you have a lot of attachments you wouldn't buy this bipod anyway and if you wanna run with a bipod and a grip this lets you get that grip as far forward as you need too.
