Removing carbine hand guard, any advice ?

[kyron4]

I just got done welding up my 21mm socket tool to remove the hand guard nut on my EVO carbine. In addition to the 1/2" drive on the end I made the tool as a "T"  handle tool to keep even torque on it. I've been soaking the nut threads down with Kroil twice a day for a week in hopes of soften the Loctite. The idea of clamping a poly receiver in a padded vice and torqueing on that nut is unsettling to say the least.  My fear is I apply to much torque and twist the barrel trunnion in the poly receiver and ruin the gun. Would a impact wrench set on 60-80 PSI work better than brute strength and a breaker bar ?  Do I leave the bolt in or remove it ? Any advice ? -Thanks

Leave the bolt in and clamp it around the trunnion area.
I haven't had any issues doing this with hand tools.

PB Blaster eats loctite pretty good. or just take a torch to your tool before going after the nut. a 700 degree socket should work quiet well  .

I got it !  Not bad at all , the nut broke loose fairly easy but dragged with resistance most the way off. They used blue Loctite on the nut, and only a dab. It turns out to put the pistol hand guard on I need the spacer that goes behind the nut. I'll start a new thread about that.

Use the same spacer that the carbine handguard uses. In fact, I used the carbine nut and spacer when I converted my carbine to SBR.

Duh ! it was stuck inside the hand guard and I didn't see it. I got now -Thanks !

I'm glad I found you guys!  I was trying to get the Mlock carbine handguard off my pistol last night! I just bought a CZ EVO3 SL1 pistol with flash can. I?ll be sending my form 1 in this week. I came here for Some Help removing the hand guard.

I was going to attach an HK Parts 3 Lug adapter to my bbl so I could run my suppressor under the habdguard  but I don?t think that?s going to work. I couldn?t tighten the adapter. Looks like I?ll be buying a micro bbl with a 3 lug from ILWT. They can engraved the bbl for me too. The  bbl and Trunnion get me two compliance parts for 922r right?

OP can you show us a photo or of the he tool you made?  Would a deep socket and long extension work? I was thinking a socket on a breaker bar. The biggest I have is a 19mm. I'll fix that tomorrow.

On the flash can model a deep socket and extension will work.

You can get 3 922r parts with barrel, trunnion and handguard.

Thank of you!  This might be all I need to tighten that HK tri lug adapter. But with the price of this and the adapter I am about 1/2 to the price if the 5.3" tri lug bbl. I need the two points and would like the shorter bbl. My.45 Silencerco with the adapter is pretty long.

This is cool too.

I thanks. Their price is a little better than ILWT but his is in stock and they will engrave my info on the  bbl which I need for making my SBR. https://www.inleadwetrust.com/collections/cz-scorpion-evo-iii/products/scorpion-evo-micro-3-lug-1-2-28-tpi-custom-barrel-trunnion

You only need to make the tool if your goung over the 16" carbine barrel, otherwise a deep well 21mm on an extension will work. As to the tool I made, I cut a 21mm deep well impact socket in half (used a wired EDM at work ) and welded each half to the end of a scrap piece of 11" pipe with 1/8" wall thickness.

Yep the long carbine wrenches are only necessary for the full 16" barrel.

And the shear simplicity of the carbine wrenches is why I keep my prices down where they are. No innovation to speak of. Although mine are about to get a minor design upgrade to allow you to use either a 1/2 drive ratchet /breaker or 1-1/4 wrench.
