Stribog Short Stroke Buffer replacement

thingiverse

This is a replacement for the stock single rod rubber buffer that incorporates the short stroke spacers. The shortest is equal to the buffer + 0.5 inch spacer and allows LRBHO The middle is buffer + 0.75 inch spacer no LRBHO without modification The longest is buffer + 1inch spacer no LRBHO without modification I recommend using TPU for this, I haven't tried it with PLA however others have made regular spacers with PLA and said they work. In order to install you have to removed the recoil spring from the stuck buffer and install it on this instead. I did this to try my hand at CAD. The point of this is to eliminate the free float of the spacer when installed in front of the stock buffer. That caused me a couple of failures, but some people have 0 issues. It also eliminates the increased spring tension from cramming the spacer behind the stock buffer.
