Any ideas on how to perform a trigger job on semi auto bren MK2. I can really feel the slap on the trigger as striker resets. Is there a way to smooth this out.
Also bren mag tool and 303 mags. does any one know how to use this tool properly to fix mags. Also some pictures for you junkies.

Very Nice! Where did you get the correct sling? I ordered mine from IMA and they sent me the wrong 1! It is too short. By the time i realised it, it had been too long to send it back.
As far as trigger slap goes, i am not too sure, mine seems to function properly. Where did you get the striker? Maybe the striker is hanging down too far? I will have to tear mine apart to look at everything again for reference.

IMA for the sling and works ok, but does not sling up to well for shooting. Works good for over the shoulder carry. Wise Lite Arms for the semi auto parts bought here at Weaponeer when it was sold on this site. My semi auto motifications to lower reciever was drive tube, opt rod, striker rod, springs, trigger, and block on selector to prevent for full. The system works fine all together. I think the trigger just needs some fine tuning. I will look into it, but wanted to see if any one else felt the same or has corrected this issue.

My mods are very similar, but minor differences. On mine, i ground the sear trip, or trip lever, or what ever it is called,(the piece that goes through the square hole in the sear), so that even if the selector could go to auto, it would not work. The "bent" for auto fire is gone.
I got my striker and other parts from project guns. I missed the buy on the site. It is set up slightly different, the spring is actually on the op rod, but, it required a different, (new) recoil spring to function correctly.
I bet the slap that you feel, is the striker resetting the sear trip, but grabbing on the auto spot on the sear? Does that make sense? I will take pics of my trigger mods. Our strikes look similar. How far down does your striker sit in the rec?

That does make sense. The full auto catch is seared off like the plans on ez feed plans. The trigger slap I am feeling is coming from sear trip I believe. I just checked it out again. Do I just ease the curve on the trip lever to allow striker to slide onto the lever. Make transition smoother?

I would say yes. Just round it out a little bit more. The thing here is, be careful not to remove too much material off of it or it may not be tall enough to reset!
If you have a dremel, you could just polish the surfaces of the striker where it contacts, and the trip lever.
I use those round grey disk's. They are about 1/8" thick. They work well.
If need be, i can pull mine apart tomorrow and take some pics for you. Like i said, we almost have the same set up.
Maybe the bottom of your striker is longer/ deeper then mine? I do not feel ANY slap.

Thanks for you help. I am thinking due to how critical that this slight motification could be it might be better to try motify and curve the back part of the striker first to ease on to the trip lever like a ramp.

That is a wise choice. Might want to take a measurement of how far down the striker sits in the receiver, it only needs to protrude far enough to reset the trigger + .010. If it is much farther then that, i might be tempted to trim the excess off.
BTW, if you do decide to round the trip lever, and mess up, SARCO has plenty of parts, and great prices as well!

Any words on the Bren mag tool. Have some issues with some of the old bren 303 mags and I have this mag tool that looks like it could be used for feed lips on mags and to check space between feed lips. Does anyone know any thing about this tool or how to correct mag issues.

Ok, I have played around a little more with this idea and I am not sold that this would be the solution. The trigger slap I feel is from the action of the trip lever reseting. I think the striker moves ok over the top of trip lever, but it is when the reset goes down and the action of the trip lever has been released is what I am trying to smooth. That is what I feel on the trigger.
If that makes any sense.
I have a few lowers and have played around with both of them, and I bet they both have the same slap. This is not even that bad, but I would love to all operations of this beautiful weapon be perfect and smooth. Any other ideas?

That is fair. It could not make it any worse that is for sure. Thank you for your help, I will try it out.

Finally getting back to this post to inform everyone that adding the small angle on the stricker made the trigger slap go away. It fires like a completly differnt gun. Thanks
