Can I safely use 0.28g BBs out of a CA M15A4 Rifle?

[NS-Airsoft-Noob]

I recently ordered a Classic Army M15A4 Rifle (SP003P-1) from Canadian Airsoft, along with some Javelin 0.28g airsoft BBs from them. The reason why I purchased the 0.28g BBs was because they were in stock, and well-priced at $16.07 CAD for 3500 BBs.

After doing a little research online, it seems that either 0.20g or 0.25g BBs would be best-suited for my ordered airsoft gun, and that 0.28g BBs were typically reserved for higher-powered guns that fire at around 375 FPS and up.

Now my question is, do you people here think I can safely use 0.28g BBs in my new M15A4 Rifle (albeit with lowered FPS), without fear of the heavier BBs jamming or damaging any of the internals?

0.28s are absolutely fine to run in that gun. For outdoors, it's typically recommended. I run 0.28s in any of my guns shooting over 360 if they're available. You'll get better accuracy out of 0.28s compared to 0.25s.
