will this BCG work with a fostech echo 2 trigger?

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on November 27, 2019

Yes, it should, and you may need to mess around with different buffer weights depending on how your AR is set up in regards to caliber, barrel length, ammo, gas system, etc.

I have a Saint Victor 300 AAC. I'm looking for a brace but I really don't know which one i would buffer I would need. Recreational shooter

Expert Answer
A
Answered by Jonathan D., Gear Expert, from IL, United States, on September 23, 2019

If you are not using an adjustable gas block I would recommend the standard weight for subsonic loads and the heavy for supersonic loads. If you do have an adjustable gas block the standard should work for both as long as you adjust your gas to suit.

Micheal, guest, from NC, United States, asked on May 22, 2019

Which brace has the jp captured spring, part number- JPSCS2-15H2?

Expert Answer
A
Answered by Jonathan D., Gear Expert, from IL, United States, on September 23, 2019

The Maxim braces can not use JPSCS2-15H2, as it is for standard carbine length buffer tubes and these use a shortened proprietary buffer tube. Here is a link to the JP Silent captured springs that are compatible with this brace:

Q
lstarr, guest, from IA, United States, asked on May 05, 2019

What version of this forearm brace do I need to purchase for my Springfield Saint AR pistol chambered 5.56 with 7.5” barrel?

Featured Answer
A
Answered by Keeper, member, from WA, United States, on September 17, 2019

Hi,
For the SA Saint in 5.56, I would still go with the CQB Brace but would switch to the H2 buffer & spring combo.
The JP-SCS-XS-Heavy might be a tad too light on that calibre and barrel length.
Thank You.

Will this model work on a Springfield Saint pistol?

Featured Answer
A
Answered by Keeper, member, from WA, United States, on July 18, 2019

Hi,
The Maxim Defense CQB Pistol PDW Brace uses the SB Tactical Arm Brace and easily installs on mil-spec AR15 lowers.
So, I am pretty sure it will work with.
Thank You.
