Imbel (FN) FAL in .22lr

[Sid]

I'll dig the armourers manual out and try to come up with some suggestions for the trigger.

Weaker hammer spring looks to be all you can do, the disconnector spring doesn't seem to contribute to the recocking force like it does in an AR
I would buy 2 hammer springs, cut one down till it's starting to light strike, then cut the second one down not so far as the first. Keep the original as a spare.

I would be cautious about removing any coils from the mainspring. You are messing with the breech timing and can run into problems with feeding the first round when cocking manually.

You really can't start a thread like this and not post pic's .
PM me if you need them hosted.

Looking forward to hearing how it shapes up.

Your pictures do not show the front of the rifle so it's unclear of the type of muzzle attachment that is on it.

On the British version the flash eliminator was screwed to the barrel and retained by a round key piece with a pin through it. This was located at the 6 o'clock position on the flash eliminator. Other eliminators may be different.

For the one there is washer between the front face of the barrel and the inside of the eliminator. To fit the eliminator, it was hand tightened and the key way should have been under turned by 15 degrees. Various size washers were available to achieve this under turn. Once the under turn was achieved the eleiminator was screwed tight preferably with the correct wrench, more usually with an adjustable spanner.

If the washer that was fitted gave more than 15 degrees then the washer could be squashed and the hole through the middle reduced in size. This would affect accuracy. Depending on the design of eliminator, washer size and hole in the washer it might be an idea to check the fit. If you know someone with a lathe have a bore guage made. Turn a cylinder 0.15" diameter by 3" long. It should drop through the barrel from the breech end.

The 0.15" diameter is from memory, the last time I used a guage like that was in the Jurrasic period so if Sid is kind he might like to look up the size in the Inspection Standards part of his EMERs.

To be honest, the only way you are going to reduce the pull off weight is to change the angles on the sear front face and the hammer engagement bent. The danger is that if you over do it the rifle will slam fire or not cock at all with the hammer sliding off the sear. The weight should be 6 to 8lbs (again from memory, Sid may confirm). If I remember the hammer spring is a sealed unit, plunger and spring in a container with the end spun in. It may be difficult to separate the two. Check the plunger and spring in the pistol grip to ensure they are not binding, it can up the pull off weight.

If you decide to play with the trigger weight, have a spare hammer, sear and hammer spring assembly before you start.

Nice gun, brings back memories of the 7.62mm SLR I used to have in the 80's.

[slowcoach]

Blimey....how much did that cut and shut job cost???
Looks like an argie folder, of which huge amounts were put into store after being taken off their previous owners for not being used in a responsible manner , even more were run over by 4 tonners and landies in a bid to clear the surplus. Check that stock gouge out, could be a part of history

[urx]

um ..... allegedly its a new rifle with no Malvinas (or other) provenance

it was made as a dedicated .22lr rather than a conversion of a 7.62.
Hence its legal here. IIRC 7.62 semi is now sec 5 so even dropping the calibre to .22lr would leave the gun at its original unobtanium sec5 rating.

I beleive a job lot were made by Imbel for a South American army as training rifles. 20 were imported to Europe but the price was high then and the price for the following batch of 20 had gone up by so much they werent worth importing.
Its fairly rare as there are only 10 fixed and 10 folders unless someone knows different......

I reckon you are right on inspecting the insides...I dont plan to mess with the mainspring but have ordered some spare hammer springs for experimentation purposes.....
The stock has gone back for replacement and should be coming home over the next 2 days

ok..'messing' with hammer spring is now well advanced.
I've obtained an original CF FAL hammer spring which is ~8mm longer than the .22lr one though the wire guage is identical. I've trimmed that 5mm below that of the .22lr hammer spring and the gun now cycles subsonics with a fair degree of reliability.
I emptied a box of 50 remington subs with no jams
50 RWS subs generated 3 'short strokes where the empty case was ejected afresh one chamberd but the hammer wasnt cocked. the gtouping was improved to less than a 10p peice at 25yds on rapid fire.
50 eley match grouped inside a 5p peice at 25yds with no failures to chamber or cycle the hammer but a couple of failed case ejects (nipped in behind the breech block and jammed the hammer).
the Winchester subs did the best overall with no failures and a nice consistent group
I'll continue trialing with a few more boxes and make sure its sorted.
Most importantly ...no light strikes in evidence

Looking promising

next job is to remove the flash hider and fit the SAK mod to see how quiet it is.

That Flash hider is on bloody tight! got the right size spanner on it and not a hint of thinking about moving
