Prometheus 6.03 EG Tight Bore Inner Barrel for Airsoft AEG by Laylax (Model: Krytac Special Edition / 310mm)

"The m14 specific 500 mm barrel is not compatible with CYMA m14 EBR hopups. The hopup collar notches are not in the correct. Cyma, g&g, and Classic Army use different cuts for their m14’s apparently.

If this is what you have, then you should instead get an Angel Custom. ~ an ancient Reddit post.

Otherwise the barrel is fine and to “standard”.

"Just received the barrel in today, and after installing the barrel in my LVOA C to test fire, i had jams with every shot. I am using the stock hop up, bucking and nub that came with the LVOA C. The bb's i used are elite force .25 grams and Vtac .28 grams. I tested with the stock hi cap magazine that came with the gun, my new G&G mid cap and elite force mid caps that i received with the order, and both also jammed. The magazines that came with the bundle definitely did not work for me, so i didn't bother to try with those. After all the mags jammed i decided to take out the barrel. I put some silicone lube on the feeding lips of the bucking, then it started to feed. After a few magazines the barrel would jam up again. Any tips would be greatly appreciated. I am giving 3 stars because the bb's that did feed actually shot pretty damn straight.

"I bought this for my Krytac Crb and it works beautifully increasing the accuracy greatly and increasing the range a bit. my problem was the way it was packaged.... it was in one of those large bubble wrapped filled envelopes and the bottom part of the package was bent over itself. at first i thought it must have been ups but after unfolding the package i found that it wouldnt fit withought being folded so evike must have intentionally packaged it like that which luckily didnt damage the barrel but damaged the plastic tube that comes with it. Barrel works great but wouldnt buy from evike again due to poor packaging.....

"It faces up. Check out youtube for guides on hop up assembly or google it and you should find plenty of step by step guides on how to correctly install the barrel.
