Looks like you guys released the RS7521, and is the 7548 new as well? I don't see photos of these lengths yet online, and in a previous post you mentioned the RS7521 having some special feature?

The 7521 is just an enlogated 7519 or something?

Missed the notification on this one…..

Yes, it’s a bit longer than the RS7519. It’s ideal for a 10.3”-10.5 and a few other applications, particularly with windowed handguards.

This interests me greatly. I have a 10" .300 whisper with a handguard that goes about 2 inches past the muzzle to shroud a suppressor. I have an slr block on it now but like your design a lot more.  Do you think it would be viable to cut a couple of the support arms on top to make room for a delrin punch or something similar to turn the adjustment knob?

No (if I understand correctly what you’re thinking), but the handguard can easily be windowed to allow access. This is particularly simple with an MLOK style.

Are the riflespeed gas block measurements referencing the entire assembly or just the adjustment knob? Im trying to determine if I can fit either the rs7519 or rs7521 on a 12.5 midlength, which has 2 3/8" from the gas block shoulder to the start of the muzzle threads.

The assembly length.
