Great rail. - ZEV Technologies AR-15 Picatinny Wedge Lock Handguard

Good product. The rail has great fit and finish and is very lightweight. Locks up very tight to your upper receiver. I gave it 4 stars because I wish zev tech would have kept the original materials the rail was made of when it was made by mega. If I’m not mistaken it originally had a titanium barrel nut where the current one is steel and the body of the rail was made of 7075 t6 aluminum whereas the new one is 6061 t6 aluminum. I’m not an engineer so I’m not sure if it honestly makes a difference unless you absolutely abuse the rail. We’ll see how it holds up over time. The wedge lock system seems robust while allowing the profile of the rail to remain very slim. Be aware of accessory placement on this rail because it it is so slim that it could cause interference around the gas block. Overall it’s a great product and I would recommend it.
