Smith & Wesson MP15 Accessories

How do you all know what accessories are compatible with your rifle and where do you all shop for your accessories? I just bought a Smith & Wesson M&P 15 Tactical 5.56mm Semi-Automatic Rifle with M-LOK and would like to add an angled foregrip and possibly other stuff in the future.

Also I tried to remove the Modular Free-Float Rail System so I could clean the barrel and other parts, but after removing the three bolts on the bottom. I could only move the rail about an inch away and then it seemed like it was stuck on something. I didnt want to try and force it loose...

I am used to hunting rifles and this is my first AR, so sorry for the newbie questions...

Don’t try to take off the hand guard. There is nothing under there that needs cleaning.

YouTube can give you great advice for maintenance and disassembly. Rail accessories attach either Mlok, picatinny or keymod. So you’d be looking for Mlok accessories

Anything m-lok compatible will work

No need to clean the exterior of the barrel like that, leave the handguard on and make sure the bolts are properly torqued. The handguard probably has another bolt that acts as a fail-safe in case the others come loose, which prevents it from falling off the gun entirely. Now that the handguard came loose, you have to re-zero your iron sights, since there’s no telling whether it’s aligned the same exact way it was before.

Spend some time on r/gundeals and you’ll see a pattern of good sellers and good products that consistently get posted. That’s how I started out!

Thanks for the info. I eventually found some videos about the handguard removal and it looks like I need a special tool. Not going down that road... I will just find something that I can run between the barrel and the handguard to apply some Hoppes 9 Lubricating Gun Oil to help prevent rust on those parts. The manual for the rifle explicitly states "Before using your firearm for the first time, it should be cleaned. See the Cleaning Section of this manual". Reading thru the cleaning section of the manual shows removal of the handguard, but it does not show how to remove the one like I got which is why I went down the path of figuring out how to do that.

Update: The handguard in the picture I posted has 3 4mm bolts on the side and 2 2mm bolts directly below the 3 4mm bolts. After loosening the 5 bolts, the handguard slides right off allowing access to clean/lubricate the barrel.
