I'm not trying to make an airsoft gun fire real bullets.
I'm doing the opposite.
I love my lower and want to get some tactical rolls and Chris Costa moves in while I fire harmless airsoft pellets.
Is this possible?
I googled this and it's never been asked before.
I was Airsoft tech from 2005 to 2013. I built and repaired close to 3000 guns. I worked for Craig L. at Federal airsoft.
Was also staff at TOLCOM in Tolland Mass, did Modern, WW2 & Vietnam events in MA, CT, Maine, and NY.
AR front end furniture for higher end airsoft guns (full floating rails) Yes and No (may have to dremel).
Depends on the airsoft base gun - Airsoft M16/M4/AR Barrel Nut's are USUALLY the same diameter and width.
I have put real steel front end keyhole rails on airsoft guns with no modifications and bolt on just like a real one. (More $$$)
Q&A Stuff:
Will Airsoft front end furniture fit on real steel? Yes. The quality will be lower and the metal thinner. You MAY have to modify. (Check install instructions and what type of airsoft gun it goes on.)
Can rear airsoft stocks be used? Possible depends on the style of stock. Telescoping stocks may not last long term due to recoil.
Can an Airsoft AR Lower be converted to real steel? NO. Thin metal, and is missing most of the entire cavity.
Can you put real steel mags in airsoft guns? YES. AFTER heavily modifying. I converted a couple of real surplus HK and FAL mags to Airsoft.
Can Airsoft Mags be converted to real steel? NO... No feed lips.
Can a real gun fire airsoft bb's? YES. A company called MAD Bull made 12 guage shotgun shells which held BB's and Gas.
You loaded them into any real shotgun to shoot 16(?) bb's at once. They made a limited batch run and were made for training LEO's on a budget.
I am also of guilty of converting a De-milled an MG42 and a 1919a4 to airsoft... Please forgive me...
Cheers!
