*Disclaimer*
This may not be the most thorough or scientific test, and if any of you think it should have been conducted differently, I'm willing to do it again.
While I've been reading a few other forums and studying them to see who is speaking the truth about all of these new gas piston upper AR variants I came across a statement that the LWRC short stroke piston bolt carrier may run cleaner than a DI gun, but the chambers were dirtier due to the design of the rifle and the POF guns ran cleaner. Well, I don't have a POF gun to compare it to the DI or short stroke LW rifle, but this is a myth and my 80rd test proved it.
I don't think anyone will debate that the M4 runs even dirtier than the 20inch A2 version, so I think comparing the Bushmaster XM15E2 20inch to the LWRC is a fair test. The cleanest Direct Impingement AR vs. the Gas Piston LWRC M6A2.
I did a previous gun cleaning review here
LWRC Review with a more thorough cleaning test, and that was after firing 260rds.
All guns were thoroughly cleaned before conducting the test and all chambers were run dry so that I would have CLP making the patches harder to view. This is a dry white patch vs. dirty dry chambers.
The clean patches did not touch anything but the chambers, and this is a chamber only test.
How the test was conductedAmmo used- 26.1gr of WC844 with a 62gr IMI - my person M855 Clone loads.
1st Round- I fired 20rds through each gun and disassembled them and twisted a cleaning patch around inside the chamber for 10 rotations.
2nd Round- I fired 30rds through each chamber and disassembled each gun and twisted a cleaning patch around inside the chamber for 10 rotations.
3rd Round- Fired another 30rds through each rifle for a total of 80rds in each and conducted the same patch chamber cleaning.
Even though the chambers were cleaned after each firing to some degree, the Bushmasters chamber still was dirtier than the LWRC.
The bolt carrier on the LWRC ran cleaner and so did the chamber IMHO this is PROVEN.
Any questions?
