I havent got them in yet ,but as far as I have told by the company they fit weaver rails. I wanna get just one to try out first to see if they are any good before I make any for sure price ,If they arent durable I wont sell them at all . they are just clones for airsoft and I may be able to sell them cheaper than what I posted.It depends on the quality and how many I purchase ,so if I get a better deal so will you guys. not to mention you guys on this forum will get discounts !!
I think they would only look good on certain rifles though, SR 25's and things like that . The m324 my brother had ,he had a fore grip on it and he loved it.He said it felt more comfortable for him and it didnt look too bad either! his bipod was also on the same long rail though.
