Just picked the above up as a club gun, trying it out last night and it not running as it should
It's had a clean,oil etc but still jams fails to fire and not pick up rounds most things you don't want a semi auto to do befor we let it loose on club members. Tired blazers eley club and a few others you get 3 ish rounds out then stops for one of the above reasons. It's having a a deep strip down clean oil and general fettle today

Has anyone got any tips on how to get it running reliably have seen a few posts on the AR15 site but with the wealth of knowledge on here I hope some can help

Cheers all
 
Tried blazers worked slightly better but only 4 or 5 shots at best before a stoppage anything should run on blazers lol
 
Tip #1: use least waxy rounds you have, copper washed tend to be better (CCI AR semi-auto tend to run well in most guns).
Tip #2: use very very little oil i.e. wipe on & wipe off.
Tip #3: ensure the extractor is clean, not worn and moves ok.
Tip #4: strip and clean the magazines (often neglected).
 
Are all the stoppages of the same type, i.e. fail to extract properly, fail to eject empty case, not moving sufficiently to rear to pickup next round, or random 🤔
 
Double feed feed but no firing pin trapped case then you get 3/4 of a mag out it then back to 2,3,4 rounds
 
In a Bremmer .22LR M16 lookalike that I once owned we found that Eley Semi-Auto ammunition worked well at reasonable cost as did most American good quality "recreational" .22LR ammunition.
 
 
Thanks done some more digging and it looks like the mags are at fault , the inside slide sticks and looses upwards pressure the hack looks like taking the mag apart smoothing everything inside then the side slide button can be taken out or the lugs removed which solves the problems ( apparently lol ) so going to try one mag and forward the results
