Unfortunately, we do not carry the screws separately. I suggest reaching out to Leapers directly.
This handguard requires the use of the proprietary UTG PRO Rail for Super Slim Free Float Handguards, which can be found by using the link below:

Yes, the UTG Pro AR15 15in Super Slim Free Float Handguard should work with that set up.
The Aero M4E1 has the hamdguard mounting system forged into the receiver and therefore is only Compatible with Aero Precision Enhanced and Quantum Series handguards.
This rail will fit and function just fine as long as you as using a lo profile gas block.
Please email us at techsales@opticsplanet.com so we can further answer your question.
Yes it does.
No, this is for AR-15, it will not fit .308 models.
It will not fit unless you replace the gas block.
Any low profile gas block should work, if your barrel has a standard .750" gas block journal, Leapers makes one of their own: https://www.opticsplanet.com/leapers-utg-ar-15-micro-gas-block.html
