I was at the Range yesterday and I saw a guy
bump firing an OLYMPIC ARMS AR,Sounded Real good.Tried it with my COLT M4 and it just wouldn't do it.Asked him about it he said he's got a couple of AR's and the OLYMPIC ARMS AR
is the only one he can bump fire ? something
Different about OLYMPIC ? can I add some  of their parts to my COLT to get it to Bump ? If so what parts ? anyone Know ? Thanks.....

For the love of [b]god[/b] do [b]NOT[/b] change parts in your Colt [:D]

Factory OAI rifles tend to have smoother triggers. This due to their manufacturing processes.

The trigger on your Colt is probably heavier.

That said, ANY semi long arm, and quite a few pistols, can be bumped. Just takes practice. I watched a friend bump his Saiga 12 gage a couple of weekends ago. Another fella bumped a Garand and an M1A.

I Didn't change anything in my COLT except I did that 15 min. trigger fix,I have extra springs tho if I want it back to stock,I was just curious........

My bushmaster trigger sucks but dumping 30 round mags in less that 3 seconds poses no problem, try putting your finger through the trigger guard and hooking it on a belt look.  Pull the handguards forward and keep you trigger hand still.
