Former G-Unit member Young Buck has reportedly begun his publicized 18-month jail bid after recently being convicted on a gun possession charge.

According to reports, Buck Marley checked himself into jail Monday (August 6) afternoon.

Young Buck is back in prison … TMZ has learned the former G-Unit rapper has officially begun his 18-month sentence for gun possession. Sources connected to the rapper tell us … moments ago, Buck checked into Yazoo City Medium Security Federal Prison in Southern Mississippi. As we previously reported, federal agents recovered multiple guns in Buck’s home during a 2010 raid. At the time, he was prohibited from possessing any sort of firearm because he was already a convicted felon. (TMZ)

Last month, the Southern rapper spoke on what he would do with the little time he had left.

Buck is spending time with his family and working on music in the limited days leading up to his incarceration. A free agent, no longer signed to G-Unit, Buck is just looking forward to starting anew and finding a new home. Months back, rumors sparked of him signing with Rick Ross‘ Maybach Music Group or his former label home, Cash Money. Truth is…Buck told XXL that either imprint would be a good look. “MMG has a real push for what they got going,” he said. “I came up with Cash Money, so just to see what they’re doing… But the height of Buck is coming out this penitentiary.” (XXL Mag)

The Nashville, Tennessee rapper recently reflected on getting hit with jail time.

“I’ve always felt the things you go through in life, it make you exactly who you are,” Buck said in an interview. “I’ve had some rough times, I’ve been fighting the bankruptcy situation as well as the court situations but, um, I will say far as David, my pride is through the roof. My head is held high and I’m just looking to get all this behind me. I can sit here all day and go about how I feel I was wrongfully mistreated in certain different areas, but the fact of the matter remains — certain things I’ve been held accountable for, I’ve just got to handle it. I appreciate all the support — I think that, um, for the most part, I’ve never really had a real lengthy criminal history. So I think with the judge not really considering my criminal history, to subtract the time, I’m just thankful for what time I do have being that I don’t want to do no time but it could have been a lot worser that what it actually is. At this point, man, I’m just trying to move forward, put everything behind me, thank-you to everybody out there that’s supporting Young Buck and I appreciate the love.” (Back On My Bucksh*t)

Young Buck received his jail sentence in mid-July.

Multi-platinum rapper Young Buck was sentenced Friday to three years in prison after he was convicted on weapons charges. Young Buck, a Nashville native whose real name is David Darnell Brown, was arrested for possessing weapons despite being a convicted felon following a stabbing several years prior. The judge sentenced the rapper to serve his two counts concurrently, so he will spend a total of 18 months in jail. “With the judge not considering my history to subtract some time, I’m just thankful for what time I do have,” Young Buck said.
