Magpul!
I don’t often care to spend the extra cash on something so trivial as nuts and bolts. And you can literally buy a generic pack of these for like 20 for $5. But, if you have an mlok rail without a lot of space, and try to mount anything near the gas block, you’ll realize quick that them generic, skinny, long bolts won’t work. So, I ordered these as they came with 2 separate length bolts. And lo and behold, they are like TWICE the diameter of them crappy generic mlok bolts. These things are BEEFY! And the short ones didn’t touch my gas block, deflecting my barrel. I bought a few packages as all my magpul items come with them (barrier stop), so I kinda had some first hand knowledge of these fatties!! Just wanted yall to know too!! They come pre threadlocked, and ready to rock. This is an item I refuse to go generic on!!! They hold my $400 cloud rein!!! They hold my $130 vertical grip! They hold my mlok pressure pad mount!! This $5 holds almost $1000 worth of items on my rail. And at only $5….why go cheaper!?!?

T-nut
What I have found out, the knock offs, some are just ok at best, if your going to use a Magpul M-lok system use oem hardware, such better quality and guaranteed fit.

Always good to have extras
Magpul is one of the best in terms of firearm accessories and having extras of a small parts like this is generally advisable. I use their stocks, mags, slings and their mlok parts are also very reliable.

Can never have enough of these on hand. You never know when you will lose one. I just wish they included more of the T nuts

They do what they should do
A Torx version would get a 5 star rating. I don't like Inbus because the edges fray, always

たかがネジ...
と思いますが、MAGPULスキーとしてはMAGPULの刻印だけで喜べます。 後ネジ穴ナメないのが良いね。
