Lm4 bolt catch (new version)
Posted 18 February 2014 - 05:05 AM
I have a question about BoobieM4H youtube video's to modify the originale bolt catch so it goes higher and catch the bolt. The spring that comes out needs to placed back after I take some material off the bolt catch and bending the level-arm ?? For the KWA LM 4 PTR GBBR it is...
Thanks for your informations.

- It shoots across the room as you take out the block never to be seen again
- It goes under the bolt release allowing it to remain disengaged until the mag engages it

You need a spring behind bolt catch so it's held OFF unless held by the bolt carrier and it releases when the charging handle retracts the bolt slightly. If you put the spring and plunger back in their original positions the bolt won't go forward unless you press the bolt catch -- defeating the whole reason for this.

The metal in these airsoft guns is much softer than in the M16 rifle and closing the bolt by pressing (or "slapping" it like in the movies) will wear the bolt stop and face of the bolt carrier fairly quickly. This modification makes operation of the gun more realistic and minimizes unnecessary wear.
