Questions & Answers
Will it allow factory 9mm Colt bolt lock back with bolt hold open? Kynshot heavy 9mm hydraulic buffer mention it will but this version doesn’t say! Manufacturer Answer

Yes it will, however, in order to use the RB5020SS, you will need to use an A5 buffer tube with a .308 carbine spring and a spacer.

Will this work with a faxon bcg and jp 308 buffer spring? Expert Answer

This buffer is intended for lighter, competition type 9mm ammunition loadings for best performance and longest service life. You will likely need to utilize additional spacers and use a rifle length buffer tube when using an un-modified BCG. Email us at Techsales@opticsplanet.com for more information.

Product Info for Blitzkrieg Components RB502SS 9mm Competition Short Stroke Buffer

Get the soft recoil impulse and quick sight recovery youre looking for in your ultimate competition PCC AR15. The RB5020SS buffer provides longer length and more weight for those who desire a short stroke competition action. With a length of 5.3'', this buffer will shorten the stroke of the bolt by 1.3'' compared to our standard 9mm buffer when installed in a standard AR15 carbine buffer tube1. This is normally a shorter bolt stroke than most AR 9mm builds will function with and is therefore not recommended. When this buffer is installed in an A5/AR10 carbine length buffer tube this buffer will shorten the stroke of the bolt by .55'', which can be increased by the addition of spacers2. Using this buffer in an AR10/A5 length carbine buffer tube is the recommended set up. AR15 carbine buffer tubes are 7'' long on the inside. A5/AR10 carbine buffer tubes are 7 3/4'' long on the inside. The damping level of this buffer is intended for lighter, low power factor, competition type 9mm ammunition loads for best performance and longest service life.image
