Will your GB in these pics fit under a Wedgelock?

The Wedgelocks are tight, but all our gas blocks do appear to fit them.

Using a SOLGW rail, tried to fit a t-nut under your gas block. It is a no go without modification. Plenty of clearance other than that rail attachment restriction.

I'm thankfully not going to need to put mlok in that area.

Thanks for the feedback. I’m assuming you’re referring to a MLOK T-nut not fitting only at the 6:00 slot under the gas block? The sides and 45° slots fit?

Correct. 6:00 is the problem. Even if you shaved the m-lok screws flush with the nut, they touch. You would have to shave the gas block and the t-nuts for it to fit. It's doable but not ideal. I'm building an 11.5 and my BCM foregrip falls into an area where the nuts aren't in that area. With that length barrel and handguard....I'm good.

Understood, thanks again.

Returning from dormancy on M4C, I’ll give my update on my first gen 16” intermediate gas OPT barrel. Past 5k rounds. Lost count. Zero malfunctions. None. It’s not lost a single bit of accuracy.

That is all.
