Sam Pascoe Posted December 23, 2016 Share Posted December 23, 2016 soo i have this A&K m4 casv, but I'm looking to increase the range. The gun is completely stock, the range is okay, but id reallyyyyy like to be able to increase it. Here is a link to the rifle: http://www.patrolbase.co.uk/airsoft-m4-m15-m16-variants/a-k-m4-casv-black-dark-earth.htm#.WF1MjaOcY_U Notes: I usually use .25 grams. Many thanks, all help is appreciated Link to comment Share on other sites More sharing options...
Guest PT247 Posted December 23, 2016 Share Posted December 23, 2016 Put in a better quality barrel (Prometheus 6.03mm//PDI 6.05mm). PTFE tape the bucking to the barrel. Chrono it, if below site limit upgrade spring to one that puts it at your site limit. Link to comment Share on other sites More sharing options...
Supporters jcheeseright Posted December 23, 2016 Supporters Share Posted December 23, 2016 Get a better hop bucking too. Firefly soft and Prometheus purple are very good for the 300-350 FPS bracket. Link to comment Share on other sites More sharing options...

Firefly soft and Prometheus purple are very good for the 300-350 FPS bracket.Wouldn't buy firefly at the moment. Last 2 I have used have torn around the feed lip in under a 500rnds. Don't know whats changed but the quality has been well off. Link to comment Share on other sites More sharing options...
Supporters sp00n Posted December 23, 2016 Supporters Share Posted December 23, 2016 If all else fails, you cannot go wrong with a G&G green rubber edit :- forgot to add is the current barrel/bucking clean?? Link to comment Share on other sites More sharing options...
Hangtight Posted December 23, 2016 Share Posted December 23, 2016 Buy the new bucking, but before you install it try flat hopping your old one, eraser nub, PTFE tape or dental floss to get a good air seal and a bag of decent 0.3g BBs. Make sure the barrel is clean and see if you get an improvement for the grand total of next to bugger all. Link to comment Share on other sites More sharing options...
