I need some help

[ryche_me 0]

Hey guys i all of a sudden find myself needing a hammer and the lock plunger for a JLMG. The lock plunger is the part that hold the upper and lower rec.s together. I thought i had everything, when i acquired some new parts for my semi JLMG project. I then find that i'm missing those parts. Is the hammer strut and spring the same parts between the JSAR and the JLMG???? Gun Parts shows that they are but, i want input from others in the know. THANKS RYCHE
