This set includes:
creep reducing shaft size 1 (1 pc)
creep reducing shaft size 2 (1 pc)
 
These creep reducing shafts are only usable with Nord Arms triggers and only with the following models:
NA-TR223
NA-TR223-S
NA-TR223-M
NA-TR223R-M
NA-TR308
NA-TR9
NA-TR22
 
For Colt type AR-15 lowers (with .169" trigger pins) see Colt-specific product NA-TR-SECRSSC.
 
Due to trigger's, lower receiver's and safety shaft's manufacturing tolerances and wear, your Nord Arms trigger may express some creep (here: any positive trigger movement) while safety selector is engaged. None of our triggers have much of pre-travel and have short pull (creep), so too much of trigger creep while safety selector is engaged may affect your rifle safety! Safe trigger creep while safety selector engaged should not exceed 0,20 mm / 0.008" (measured between safety selector's shaft and trigger's tail).
 
NB! Do NOT use screw trigger adjuster installed inside pistol grip bolt with Nord Arms triggers! This will not only reduce trigger creep while safety selector engaged, but also reduces overall trigger creep (here: any positive movement before break) as our triggers don't have much of pre-travel, possibly leading to unsafe operation of your rifle! With our triggers, only use our creep reducing shafts!
 
Two different creep reducing shafts are not included with all our triggers, only with match trigger (size 1 and size 2), that will normally take care of all excessive creep. For two more adjustment options or if your creep reducing shafts are missing, this shaft set is needed.
 
One set of creep reducing shafts will raise trigger's tail as follows (distance is the distance between safety selector's shaft and trigger's tail):
 
Distance  -  front shaft  -  rear shaft:
0,20 mm / 0,008"  -  size 1  -  original
0,35 mm / 0,014"  -  original  -  size 1
0,40 mm / 0,016"  -  size 2  -  original
0,70 mm / 0.028"  -  original  -  size 2
0,75 mm / 0.030"  -  size 2  -  size 1
0,90 mm / 0.035"  -  size 1  -  size 2
 
The second set of shafts adds two more options:
0,55 mm / 0.022"  -  size 1  -  size 1
1,10 mm / 0.043"  -  size 2  -  size 2
