Extra picatinny screws strip out - UTG Pro AR15 15in Carbine Length SuperSlim Drop-in Handguard

I bought this handguard about a year ago and mounted a large 12" leg length leapers bipod on the bottom of the handguard to an attached picatinny rail and then locktited the screws in and they held for about a year. I only used my rifle about 10 or 12 times for shooting from a table top at the range so the handguard was not beat around or mistreated. The screws that mount the extra picatinny rails that come with the handguard are not strong enough to hold my bipod. The front screw on the attached picatinny rail completely pulled out of the handguard.

I ordered another handguard like this one but decided on the m-lok version as m-lok is a much stronger mounting system. I do like this handguard but I don't think the screws in this version are enough for a bipod. I did not call leapers as I don't want another handguard that is like this one to replace it as it would fail again. Just an expensive lesson. I can still use it on another rifle without a bipod.
