A friend who is a new LEO was discussing with me the options of installing an SBR upper (specifically a 10.5" from DSA) to his issued M16 lower and BCG. Is there any issue with gas tube length, timing, or anything else that would stand in the way of a successful drop in install?
Yup, skydiver's research is correct. A heavy buffer will usually make the 10.5" run fine... BUT... this can depend on ammo choices, use of a suppressor and a few other mysteries of life thrown in to the mix. My 10.5" SBR runs like a top with just going with the heavy buffer but I have only run Federal 5.56mm ammo, I have not used reloads, and I do not yet have a suppressor. A friend of mine does use a suppressor and his 10.5" runs 100% with just a heavy buffer. Your friends results may vary and if so then it's just a matter of trying different combos of springs and buffers and I have seen where some guys go with a pneumatic buffer which are adjustable.
Thats great, the buffer/spring is a pretty simple and inexpensive component to mess with. Thanks for the great info guys. Ill pass this on to him so he can start experimenting.
