2014年12月9日 · My SBR is a Noveske 10.5" Switchblock which is already a little front heavy being a heavier barrel profile. Has anyone else experimented with these combos on their SBR? What were your observations? I run a UBR on my 13.7" rifle, it helps counter balance the suppressor. I also like being able to extend the stock to a preset position.

2016年7月31日 · It's a lot of money and a fair bit of work, but I'm super happy with this 300BLK SBR's stock. It's a Minimalist stock that I cut down to fully collapse and bottom out on a LWRC ultra compact stock receiver extension. Inside is a short JP silent captured spring that came with my Maxim Defense CQB stock.

I decided to upgrade the stock from a Magpul MOE SL, to a Magpul UBR (Utility/ Battle Rifle) for a better cheek weld and reduce the kick of 7.62

2019年8月10日 · The SBR is well-mannered thanks to the recoil-absorbing, SureFire SOCOM 2 556 QD suppressor. Splits are fast and the muzzle confidently swings between targets without over-running them during transitions since the gun is well-balanced.

The first thing you notice is the new stock is much lighter. The weight of the Gen 1 is one of the complaints many tactical users had of the Gen 1 stock. At 26.1 ounces the Gen 1

2019年10月5日 · I am reconfiguring my of my SBR's and I am looking to get some opinions on installing a Magpul UBR on it. Currently I am running a B5 SOPMOD which weighs in around 7.5 ounces. With some of the front end accessories especially the suppressor it is throwing the balance way off. Any thoughts on using a UBR to balance it out?

2007年10月2日 · Anyone run an SBR in 458 SOCOM? If so, how short? Reliability issues? Thinking of setting one up to take backpacking in bear country as bear medicine.

2015年3月17日 · Currently I have an AR Pistol that I've been wanting to SBR since I suppressed it (The new ATF ruling just gave me more reason to do it). Now the question is, which stock to put on the SBR. I was debating between the UBR and the CTR stocks
