Jwbfx4 Posted September 22, 2019 Share Posted September 22, 2019 So I just got into shooting a pcc in matches not long just for fun. I bought a complete NFA lower and upper. Been very happy with it so far and no issues. As I was researching and going through topics here and elsewhere I knew some things to look out for. I asked the people at NFA about the weight of the buffer and spring, and was told the right one will come with it. Now I haven’t had any issues but I did notice the bolt comes a good ways back past the bolt catch. Looks like I need a spacer to decrease the travel. My question is does adding a spacer change the feel of the gun? By that I mean recoil or more of a bounce to it? I like how it feels currently but in reading it makes me concerned about potentially breaking the bolt catch at some point. Just wondering what your experiences have been. Thanks. Link to comment
Acer2428 Posted September 23, 2019 Share Posted September 23, 2019 Yes, tons and tons of info out there. In ye olden days we started with quarters. You can add/subtract to your liking. Then once you get the length you can cut a delrin rod, etc. Thankfully we live in modern times and you can go out and buy a short stroke kit from taccom, JP, etc. If you don't like it, re-sell it for a small loss. If you keep your bolt catch AND full-length travel you WILL eventually break your catch. Link to comment
Les Snyder Posted September 23, 2019 Share Posted September 23, 2019 my buffer spacer came from New Frontier Link to comment
Startingover Posted September 24, 2019 Share Posted September 24, 2019 I would try the wave spring and a quarter, as a cheap starting point. Link to comment
Jwbfx4 Posted September 24, 2019 Author Share Posted September 24, 2019 I’m actually headed out the morning to do some testing with it. I’ve got a bunch of Deleon rod at the shop so I’ll try to figure me out a length today and see how it feels. Link to comment
MemphisMechanic Posted September 24, 2019 Share Posted September 24, 2019 The shorter the stroke, the flatter the gun shoots. It will hit your shoulder harder, but the dot won’t move as much. It’s rare to find a really well setup PCC where the gun can be locked back. Most of them are destroked too much for the bolt to come back far enough. Link to comment

But looks like I have a little more testing to do. Link to comment

I just wondered if there was a consensus among those that already do this what the best length is. Link to comment

Start around 6-8 quarters and test it for your grip and whatever load your shooting. Link to comment

If you have the Taccom buffer you can get their short stroke spacer for it. It comes standard now with their 3 stage buffer kit. I dropped in the entire kit with my QC10 lower build and haven't looked back. Has worked great for over 2k so far. Link to comment
Aircooled6racer Posted September 26, 2019 Share Posted September 26, 2019 Hello: Try using the quarters first to see if you actually like the shorter stroke. I have tried different setups and actually like the longer stroke setup. I do change the JP weights and buffer spring for my 131-134PF loads using 124's. I like to be able to lock the bolt back as well. My setup is not full stroke but enough to be able to use the bolt catch. My other setup is using a AR-15 carbine buffer with a weight change. Thanks, Eric Link to comment
CalTeacher Posted September 26, 2019 Share Posted September 26, 2019 I use a hydro buffer and a weighted spacer between the bolt and buffer. It minimizes muzzle rise and has solved the problem of destroyed blitzkrieg buffers. Link to comment

CalTeacher Posted September 27, 2019 Share Posted September 27, 2019 It’s on blitzkrieg’s website. I also made one out of delrin and it works great. I did have to mill it down .1” to allow my trigger to reset reliably. Link to comment
