This means taking away the grittiness of the finish, not changing the shape. The second way is to (lightly) polish the sear surface and/orВ sear ledge. Obviously you test this with a dummy round. If the firing pin drops while you are cocking it, there is not enough positive sear engagement вЂ“ with enough force, you made the firing pin go right over the sear and hit what would be a live round. I like to check this by ramming the bolt home as hard and fast as possible. This method is reversible, and with thorough testing of the trigger mechanism is the safest way of adjusting the sear. This means less effort is required to break that engagement, dropping the pin and firing the chambered round. This will move the trigger to the rear and lower the sear in relation to the firing pin вЂ“ i.e.В less of the sear is engaging the firing pin. The first way is to adjust the grub screw behind the trigger. If you donвЂ™t have a punch set handy, you can readily make your own with some nails and a grinder. The last thing you want is a rifle that will go off when you bump it. There are threeВ ways to adjust the sear on the JW-15, andВ noneВ should be attemptedВ without a serious level of confidence or skill. It can take a perfectly safe firearm and make it a loose cannon. Sear adjustment вЂ“ itвЂ™s your callДЄdjusting the sear is a risky move. If itвЂ™s brand new, youвЂ™ve got a lot of grease to remove before you get to this point. Just about every part of the trigger could do with at least a polish. PolishДЄ lot of the machining on the JW-15 requires some work with a file, sandpaper and grinding paste to get to an acceptable level. IвЂ™ve not found a pen spring that would do the job, but you might. If you are not so bold or would like to return your firearm to original spec one day, replacing this spring with a lighter/shorter one will do the trick.В I know of some people who have used springs from ballpoint pens. Beware though, that if you cut off too much, the trigger wonвЂ™t spring back into place after youвЂ™ve pulled it вЂ“ which makes it pretty useless. I simply cut off a few coils to lighten my spring.

With such a blank canvas, there is plenty of room for improvement with this trigger. ItВ can be gritty withВ excessive over-travel (a symptom of the Mauser-style trigger not absent in the Brno), but the ones IвЂ™ve tried all break like a glass rod at weights that are not excessive for average shooting. The trigger on the JW-15 is not pretentious at all. One of the first things you can improve is the trigger.

I agree with those people 100 per cent, but I also think that with a little bit of elbow grease, this humble Brno-clone can be a decent shooter. An implement meant to be thrown on the quad bike or back seat, and touted around the farm for practical purposes. There are many that will say that the Norinco JW-15 is an excellent tool.
